goodolclint-claude[bot] 61ac247408 fix: honour OVF bus type, correct the SCSI/SATA controller mapping, and validate the descriptor (#165)
Import-PveOva ignored disk.BusType and always assigned scsi{i}; the
controller-mapping helper itself had CIM ResourceType 6 (Parallel SCSI HBA)
and 20 (Other storage device, VMware's SATA AHCI controller) swapped. Both
are fixed together since honouring BusType is what makes the mapping bug
observable. The cmdlet now tracks a running index per bus (scsi/sata/ide),
falls back to scsi for an unrecognized or missing bus type, and refuses to
emit a slot number beyond what PVE's qemu-server schema accepts (ide0-3,
sata0-5, scsi0-30), overflowing to scsi and erroring out before upload if
even that is exhausted.

OvfMetadata also trusted the OVF descriptor's ovf:href attribute (an
attacker-controlled disk file name inside a downloaded OVA) unvalidated,
letting a crafted href inject extra keys into the comma-separated PVE
property string written for import-from. hrefs are now checked against
^[A-Za-z0-9._-]+$ and rejected outright if they are exactly "." or "..",
closing a path-segment escape the character class alone did not block.
The regex is anchored with \A/\z rather than ^/$ so a trailing line feed
cannot slip past under .NET's default multiline-$ semantics.

The descriptor is now parsed through XmlReader with DtdProcessing.Prohibit
and XmlResolver = null instead of XmlDocument.LoadXml directly, closing
the internal-entity-expansion memory-exhaustion route a hostile descriptor
could otherwise use.

ParseOvfXml is now internal (assembly already has InternalsVisibleTo the
test project) so the new tests can drive it directly with inline OVF XML
strings instead of building TAR archives.

Reviewer findings acted on (Codex, correctness-reviewer, security-reviewer,
run in parallel against the working tree): the dot/dot-dot href bypass and
the missing \A/\z anchoring were found independently by all three and
fixed; the bus-slot ceiling was found by two and fixed. Findings not acted
on, with reasons: validating the local -Path OVA filename the same way
(security-reviewer, medium) — that name is operator-supplied, not drawn
from the attacker-controlled archive contents the issue names, and touching
it would widen the change past the two issues' stated scope; percent-
decoding/loosening the href character class to admit spec-legal names with
spaces or encoding (security-reviewer, correctness-reviewer, medium) —
issue #148 specifies this exact character class, and loosening it reopens
the property-string injection the issue asks to close; capping the raw
byte size of the extracted .ovf entry against decompression-bomb exhaustion
(security-reviewer, low/medium) — a distinct DoS vector from the DTD
entity expansion issue #148 names, not part of its stated scope; branching
CIM ResourceType 20 on ResourceSubType to separate SATA from NVMe
(security-reviewer, low) — issue #138 specifies the 6/20 mapping exactly
as fixed here. An existing Integration-tagged Pester assertion
(tests/PSProxmoxVE.Tests/Integration/12_OVA.Tests.ps1:66) checks
$config.Scsi0 specifically; if that suite's fixture OVA ever carries a
type-20 controller the disk will now land on sata0 instead and the
assertion will need updating — left alone here since it is excluded from
every offline run this change was verified against and touching it without
being able to run it against live PVE would be guessing.

Closes #138

PSProxmoxVE

Build Unit Tests Integration Tests License: MIT PowerShell Gallery

A production-grade C# binary PowerShell module for managing Proxmox VE environments.

Supported Proxmox VE Versions

PVE Version Status
9.x (current, 9.1.6+) Primary target — fully supported
8.x Supported
7.x (7.0+) Best-effort — core cmdlets work, newer features emit clear version errors
6.x and older Not supported — hard blocked by version checks

Version Gating Policy

The module uses a two-tier version check for cmdlets that require newer PVE APIs:

  • Hard block (introduced version): The API endpoint doesn't exist — the cmdlet emits a terminating error with a clear message like "This operation requires Proxmox VE 8.1 or later."
  • Warning (default version): The feature exists but may not be enabled by default — a warning is emitted but the command proceeds, allowing users who manually enabled the feature to succeed.

Most cmdlets target endpoints available since PVE 4.2 and require no version check. Cmdlets that need newer APIs include SDN (introduced 6.2, default 8.0+), cloud-init management (7.2+), container interfaces (8.1+), VM disk import (8.1+), and pool management (8.1+ for update/delete).

Prerequisites

  • PowerShell 5.1 (Windows PowerShell) or 7.2+
  • OS: Windows, Linux, macOS
  • Network: HTTPS access to Proxmox VE API (default port 8006)

.NET Compatibility

The module ships as a single netstandard2.0 assembly, which runs on both .NET Framework and .NET Core/.NET:

PowerShell Version Runtime Status
5.1 (Windows PowerShell) .NET Framework 4.8 Fully supported
7.2, 7.4, 7.5 .NET 8.0 / 10.0 Fully supported

Installation

# Install from the PowerShell Gallery
Install-Module -Name PSProxmoxVE -Scope CurrentUser

# Or install a prerelease version
Install-Module -Name PSProxmoxVE -Scope CurrentUser -AllowPrerelease

# Verify installation
Get-Module -ListAvailable PSProxmoxVE
Import-Module PSProxmoxVE

Quick Start

Connect to a Proxmox VE Server

# Using username/password (ticket-based authentication)
$cred = Get-Credential -UserName 'root@pam'
Connect-PveServer -Server 'pve.example.com' -Credential $cred -SkipCertificateCheck

# Using API token
Connect-PveServer -Server 'pve.example.com' -ApiToken 'root@pam!mytoken=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'

# Verify connection
Test-PveConnection -Detailed

List and Manage VMs

# List all VMs
Get-PveVm

# List VMs on a specific node
Get-PveVm -Node 'pve1'

# Filter by status
Get-PveVm -Status 'running'

# Start/stop VMs
Get-PveVm -Name 'my-vm' | Start-PveVm -Wait
Get-PveVm -Name 'my-vm' | Stop-PveVm -Wait

# Clone a VM
Get-PveVm -VmId 100 | Copy-PveVm -NewVmId 200 -NewName 'my-clone' -Full -Wait

# Get VM configuration
Get-PveVm -VmId 100 | Get-PveVmConfig

Upload Files

# Upload a local ISO file to Proxmox storage
Send-PveFile -Node 'pve1' -Storage 'local' -Path './ubuntu-24.04-live-server-amd64.iso' -Wait

# Upload a disk image for VM import
Send-PveFile -Node 'pve1' -Storage 'local' -Path './disk.qcow2' -ContentType 'import' -Wait

Note: Send-PveFile implements a workaround for a long-standing Proxmox API multipart parsing bug (bugzilla 7389). Standard multipart HTTP libraries (including .NET's MultipartFormDataContent) add sub-headers that Proxmox's pveproxy mishandles, resulting in corrupt uploads. This cmdlet constructs the multipart body manually to ensure correct uploads where other tools may produce corrupt files.

Work with Snapshots

# List snapshots
Get-PveVm -VmId 100 | Get-PveSnapshot

# Create a snapshot
Get-PveVm -VmId 100 | New-PveSnapshot -Name 'before-upgrade' -Description 'Snapshot before OS upgrade' -Wait

# Rollback
Get-PveVm -VmId 100 | Get-PveSnapshot | Where-Object Name -eq 'before-upgrade' | Restore-PveSnapshot -Wait

Cloud-Init Configuration

# Get current cloud-init config
Get-PveVm -VmId 100 | Get-PveCloudInitConfig

# Set cloud-init config
Get-PveVm -VmId 100 | Set-PveCloudInitConfig -Hostname 'web01' -User 'admin' -SshKeys @('ssh-ed25519 AAAA...') -IpConfig 'ip=dhcp' -Wait

# Regenerate cloud-init image after changes
Get-PveVm -VmId 100 | Invoke-PveCloudInitRegenerate -Wait

Authentication Guide

Username/Password (Ticket-Based)

Ticket authentication uses Proxmox's built-in session system. The module POSTs to /api2/json/access/ticket and stores the returned ticket cookie and CSRF token.

  • Format: user@realm (e.g., root@pam, admin@pve, user@mydomain)
  • Expiry: Tickets expire after 2 hours. The module detects expiry and prompts you to reconnect.
  • Realms: Supports all Proxmox realms — pam, pve, custom LDAP/AD realms.
  • When to use: Interactive sessions, ad-hoc management tasks.
$cred = Get-Credential -UserName 'admin@pve'
Connect-PveServer -Server 'pve.example.com' -Credential $cred

API Token

API tokens provide persistent, non-expiring authentication. They are the recommended approach for automation.

  • Format: USER@REALM!TOKENID=UUID (e.g., root@pam!automation=12345678-abcd-efgh-ijkl-123456789012)
  • No expiry: Tokens remain valid until explicitly revoked.
  • When to use: Automation, scripts, CI/CD pipelines.

Creating an API token in the PVE UI:

  1. Navigate to Datacenter → Permissions → API Tokens
  2. Click Add
  3. Select the user, enter a token ID, optionally uncheck "Privilege Separation"
  4. Copy the token value — it is shown only once
Connect-PveServer -Server 'pve.example.com' -ApiToken 'root@pam!automation=12345678-abcd-efgh-ijkl-123456789012'

Multi-Cluster Usage

Every cmdlet accepts an optional -Session parameter. This enables managing multiple Proxmox VE clusters simultaneously:

# Connect to two clusters
$prod = Connect-PveServer -Server 'pve-prod.example.com' -ApiToken $prodToken -PassThru
$dev = Connect-PveServer -Server 'pve-dev.example.com' -ApiToken $devToken -PassThru

# Query each cluster explicitly
$prodVms = Get-PveVm -Session $prod
$devVms = Get-PveVm -Session $dev

# The last Connect-PveServer call sets the default session
# So Get-PveVm without -Session uses $dev
Get-PveVm  # Uses $dev session

SDN Management

Software-Defined Networking (SDN) features require Proxmox VE 8.0 or later.

# List SDN zones and VNets
Get-PveSdnZone
Get-PveSdnVnet

# Create a new zone
New-PveSdnZone -Zone 'myzone' -Type 'simple'

# Create a VNet
New-PveSdnVnet -Vnet 'myvnet' -Zone 'myzone' -Tag 100

If connected to a PVE server below version 8.0, SDN cmdlets will throw a clear error:

SDN management requires Proxmox VE 8.0 or later. Connected server is version 7.4.

Known Limitations

  • No automatic retries: Failed API calls are not retried. Implement your own retry logic if needed.
  • Integration tests require live node: Integration tests require a dedicated Proxmox VE test node. See tests/PSProxmoxVE.Tests/Integration/README.md.
  • No Ceph management: Ceph pool/OSD/monitor management is not included in v1.
  • No PBS integration: Proxmox Backup Server operations are not included in v1.
  • Task waiting: Wait-PveTask polls with a minimum 1-second interval. For high-frequency monitoring, use the PVE web UI.

Contributing

  1. Clone the repository
  2. Open PSProxmoxVE.sln in your IDE
  3. Build: dotnet build
  4. Run unit tests — import the local build first, or an installed copy of the module shadows it and the suite reports failures against correct code: pwsh -Command "Import-Module ./src/PSProxmoxVE/bin/Debug/netstandard2.0/PSProxmoxVE.psd1 -Force; Invoke-Pester tests/PSProxmoxVE.Tests/ -ExcludeTagFilter Integration"
  5. Run integration tests (provisions nested PVE, x86 only): see CLAUDE.md, "Local dev environment"
