[Mondo-devel] Trouble using mondo for Proxmox nodes...

Marco Gaiarin

I'm using mondo (apart in P2V migration ;-) to do bare metal restore
for my Proxmox-VE node.

Proxmox is, for the mondo point of view, simply a debian jessie with a
custom kernel, mostly from Ubuntu.

I've noted that sometime mondo fail on that node, and seems related to
kernel upgade: eg, if i upgrade the system (and the kernel), and i
DON'T reboot, mondo fail creating the boot image:

 [...]

My supposition is correct?
There's some way to prevent/fix that, without rebooting teh server?

Thanks.
