Hello all,

 

I have made a big mistake yesterday.

I have had the strange idea to swap my parity hdd and my cache hdd, result is I have lost all my dockers and VMs.

I do have a backup for all my vms (only the vdisk.img, no vram, no xml).

To restore my vms, I have tried to follow these instaructions:

 

Quote

To import a VM from a previous unRAID install, create a new VM with the desired configuration, including a new virtual disk. Don't start the VM at the end of the wizard. Then, go to the location of the virtual hard drives and replace the new (existing) virtual disk with the previous machine and start the VM

 

Of course, it doesn't work ... I have the grub's prompt everytime I try to boot.

My primary vdisk location is: /mnt/user/domains/freya-sdns/20231008_0000_vdisk1.img

The Bios I am using is: OVMF

 

Ideas where to start ?

Thx

I forget the diagnostic file

unc04-diagnostics-20231020-0927.zip

If you still have the old cache restore the old libvirt.img, you should always have a backup of the file.

I do have an old libvirt.img file ... 

What is the procedure to move it to the right folder ? If I change the path "

Libvirt storage location:' in VM Manager,  is it correct ?

Thx

Disable the VM service, move the old file on top of the current one, re-enable VM service.

doesn't seems to work ....

After changing the libvirt.img with an older one, I was able to see my three VMs in the VM menu.

When trying to start my Home Assistant VM, with the backuped vdmk file attached (/mnt/user/domains/UnS04_VM.HA/20231008_0000_haos_ova-10.2.vmdk) I have the Shell's prompt nothing else ....

Thx

If it's pointing to the old vdisk it should work, unless that type of VM needs anything more, but can't really help with that since I'm not familiar with HA.

From "ghost82"

 

I have created a new vm:

 

Choose the Linux or Ubuntu template instead of windows 10
Do not set the OS install cdrom
Choose VNC as graphics

Do not select a sound card (none), or select the onboard audio (do not choose hdmi audio)
Do not check any usb device

Uncheck start vm after creation
Click create

 

I have done a past and copy of the xml file from the new VM to the old one and replace the type by "vmdk" and change the file path and upload it.

Whe starting the vm I have now a "error unknow filesystem" ....
