When a guest fails to start, the GUI doesn't present you with an immediate error. Below are some steps you can try:

  • SSH into the Proxmox VE server.

KVM

  • Review the contents of syslog:
tail -50 /var/log/syslog

  • Try starting the VM from the shell. This should reveal problems that are preventing the VM from booting.
    • Note: Change VMID to the guest VM's ID number:
qm start VMID

The last step noted above made me aware that an ISO I was using for the VM's CD drive was missing. The ISO had been deleted some how. Here's the output of the command from my server:

vm3:/storage/template/iso# qm start 104
volume 'local:iso/clonezilla-live-1.2.6-24-i686.iso' does not exist

LXC

See Linux_Container paragraph "Obtaining Debugging Logs".
