Unbootable VHD backups
-
@Schmidty86 did this VM previously have a USB device that was passed through on your prior host?
-
@DustinB Yes i had a z-wave dongle passed through via USB to connect devices to my HA. But that never seemed to matter before if it was or wasn't attached. It would still boot and HA would say the device was missing.
-
@Schmidty86 You might need to go into BIOS and check to see if this now missing device is still listed, and disable it if it is.
-
@DustinB how do you get into the bios of a vm that wont even post? That also would only account for fixing one of the two VM's even if it did fix the problem.
-
@Schmidty86 Try disabling the boot devices under advanced

then you'll have more time to see what the options are to get into BIOS.
It might even be as simple as tapping the Shift Key while the VM starts.... I don't have to do it often enough to commit to memory, but you can definitely get into BIOS on a VM that "isn't posting". You've technically made it past post, and are failing due to a missing boot device.
-
@DustinB You cannot disable all the boot devices in xoa.
-
Got into the boot but, change what now?
-
@Schmidty86 I dont see your disk at all listed, only PXE (network booting) and then the MISC device (which is the questionable item).
The internal Shell isn't relevant to this conversation.

As a side thought, re-enable the DISK under advanced and then reboot into BIOS and see if the disk is listed.
-
still nothing. and i do have the vhd attached.
-
@Schmidty86 That disk appears to be a secondary disk, is this just a "data volume" and not a boot volume (looking at XO where it shows xvdb)?
Hrm as to the fact that it still shows it as a misc disk.... I'm at a loss.
-
@DustinB To my knowledge this is the bootable volume. all the other backups in the parent folder are just differential backups that are much much smaller.
-
@DustinB Also when i look at the VHD in 7zip i can clearly see that it has a boot sector.
-
@Schmidty86 Try to detach the disk and reattach, it should be xvda in order to be bootable
-
@AtaxyaNetwork Sadly I've done this multiple times as well with no luck of it turning into that format.

That's what I was thinking as well, but obviously something is off with this VM.
@Schmidty86 is the old host still online? If so you might be able to perform a Live Migration or a replication job to copy it from the old host to the new.
