proxmox Reboot while VM also reboots?

[killmasta93]

Hi, I was wondering if its possible when proxmox reboots, the VM would go to standby and would turn backup when proxmox goes online? something like hyper V as when the host machine shutdown the VM would go to standby? Because right now when proxmox reboots it turns off all the VM and when it goes online takes a while for all the VM to turn back on

Thank you

As far as I know, this is not a feature supported by Proxmox.
I would also like to note that if you manually suspend your VMs before shutting down, it will not resume normally.
The only work-around I can think of is to create a script to snapshot, shutdown, reboot, restore.

...because without RAM saved with suspend there is no RAM to recovery. And that RAM require time and storage capacity.

Thanks for the reply, i was looking around and found this article but /etc/sysconfig/libvirt-guests does not exist on proxmox any other ideas?

Or maybe i was thinking a script that would get trigered when reboot or shutdown the Proxmox host
something along the lines of

qm suspend 101

then when it start ups again would run

qm resume 101

or a script which would have a delay 5 seconds to termkill the host then suspend the vm, then when it reboots it would resume?

As mentioned before, you cannot just suspend your VMs.
You would have to create a snapshot.

Thanks for the reply, so the question is i would need a snapshot? but howcome Hyper V and VMware one could configure this way?

Thank you

Because they are a different products with that feature.
Proxmox does not have every feature every other hypervisor has and other hypervisors do not have every feature Proxmox has.
