VM missing configuration

[ejmerkel]

I have an old proxmox v3 cluster that I am working on migrating off of. I have 1 VM still running on the cluster but it's configuration file has become empty. The VM itself is still running. I assume if this node ever gets rebooted the VM will not be able to boot because there is no configuration.

Is there a way to recreate the conf file in /etc/pve/nodes/node_name/qemu-server ?

I can get some of the configuration info from looking at the current process running via "ps". Is that enough information to rebuild the conf file?

Best regards,
Eric

You have to write a new config.

Yes this information is everything you need.

I think I found a copy of the old configuration file. Does this format look correct?

bootdisk: virtio0
cores: 4
ide0: none,media=cdrom
ide2: none,media=cdrom
memory: 16384
name: chi-enz-ds01.domain.com
net0: virtio=22:326:6E:83:4B,bridge=vmbr0
onboot: 1
ostype: win7
sockets: 2
virtio0: local_lvm:vm-103-disk-1,mbps_rd=100,mbps_wr=100,size=500G
virtio1: local_lvm:vm-103-disk-2,mbps_rd=100,mbps_wr=100,size=1024G
#qmdump#map:virtio0:drive-virtio0:local_lvm:raw:
#qmdump#map:virtio1:drive-virtio1:local_lvm:raw:

Do I simply need to copy this to /etc/pve/nodes/node_name/qemu-server/103.conf where 103 is the VM ID?

Also, can I do this while the VM is running?

Thanks in advance for your help!

Look Ok.

The qmdump lines can be removed.

Correct

Yes
