Hi,
I have been running a Hassio VM for the past 6 months without any issue. Last week we had a power surge and the pc was swithed off. Now I have issues booting/starting this VM. It goes into a black mode after VM start. Anyone any advice on where to look to resolve this?

00:00:04.495117 Host RAM: 7890MB (7.7GB) total, 4508MB (4.4GB) available
...
00:00:04.966440 RamSize <integer> = 0x0000000139400000 (5 255 462 912, 5 012 MB, 4.8 GB)

Over-committment of host RAM will not be helping. I would reduce to 2048MB (or maybe 3072MB), or add more RAM to the host.

00:00:04.966705 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)

16MB is not enough graphics RAM either. I would increase to 64MB.

I see that EFI is enabled. Does this OS really need EFI? Your disk is nowhere near the 2TB limit for MBR. I see that this is in the website instructions, but given the note below I'm not sure I trust their competence.

I looked at their website: you might want to suggest to the Hassio people that they should be providing working VMs (e.g. as OVA), not bare disk images.

p.s. In future please ensure that the VM is shut down rather than copying out incomplete files that are still opened for writing. Or if the issue was attachment size, then compress (zip) the file before attaching it.

thx

will check with changes u suggested

Do not disable the EFI setting if your VM is using GPT partitions (despite not needing them).
