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
syslogandvzctl.log:
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".
