Repair a virtual machine?

Gps2010 · September 10, 2024, 3:02pm

I had a working virtual machine, and then reinstalled tumbleweed.

Most data was not on the tumbleweed disk, but on another harddisk. sdb5

Tumbleweed/ home did have a folder, related to the virtual machine.
Of course that folder is gone now.(because I formatted the nvme disk)

Can this be fixed ?

sda = windows disk, but is unrelated tot the virtual machine.
sdb is for the most part a Leap install

Yes, restore it from the recent backup of /home you made.

heitormoreira · September 10, 2024, 6:21pm

If you don’t have backup of the VM, you can recreate the VM pointing the VM to use the old virtual disk, if you still have them.

I a m trying but get an error something about qemu, owning the file.

Then had a look at fstab.

There is something missing.
Going to search for an old topic of mine, see what I need to add in there.
Then create a folder, which if I recall right, will be the mount point, fingers crossed.

Gps2010 · September 11, 2024, 2:16pm

When I try to create a new virtual machine , I am getting an message from the installer.

The emulator might not hane rights for the path ´/run /media/guus …Win 1021H1-dutch-x64.iso

I am lost, this is the iso I used before.

Its on a different harddisk, then the tumbleweed install.

Maybe I need to format, to clear out any history?

heitormoreira · September 11, 2024, 9:05pm

It seems like a permission issue. The virtualization runs with its own user, you have to configure permissions appropriately.

Gps2010 · September 11, 2024, 9:42pm

It looks like qemu owns the files.

I am probably gonna reformat that hard disk.

Not sure if I then later will install leap again.

200 gig for windows and the virtual machine, should be enough.
Then maybe two ext 4 partitions.

As we type I have two partitions, for the virtual machine.
There is some history, and there does not seem to be simple fix, with a Gparted usb, I have.

Gps2010 · September 12, 2024, 2:01pm

I made a bit of progress.

(although leap no longer starts, but that something for later, I probably know how to fix this.)

At least i now have one partition, sdb2, instead of two, for my virtual machine.

sdb2 is were I want to copy the win10 iso, but when I look under rights its root root.

How to change this to guus users?

chmod something ?

Gps2010 · September 12, 2024, 8:18pm

Need to do some more reading, there is also chown, and fstab.

Now what do I need for what I want? I do remember some parts, like that I need to be careful with fstab.

I think that the partition now gets mounted by root.

Its a puzzle, but I will get there.

Gps2010 · September 14, 2024, 4:08pm

Dolphin keeps showing me a virtual machine, how do I get rit of that ?

format the partition sdb2 ?

Could you explain this better?

Gps2010 · September 14, 2024, 9:46pm

When I use dolphin, bottom left side of the window, there are the disks it sees.

There are 3 hardisk, which should show there but…
There is also a vm, the one I a m trying to get rid of.

heitormoreira · September 15, 2024, 5:24am

Please send a screenshot.

Gps2010 · September 15, 2024, 2:26pm

Left side screen, were all disk are listed.

heitormoreira · September 15, 2024, 6:38pm

That’s just a partition labelled as VM on some internal storage device. You can use YaST Partitioner to manage it.

Gps2010 · September 15, 2024, 8:17pm

Thank you, then I might be closer to were I want to be.
Right now its way too small, but maybe this will work, because in the install of win 10, I will get asked about were I want to install win10.

I probably then can do the windows install in a partition a bit over 100 gig.

Gps2010 · September 21, 2024, 7:20pm

I think I know what to do.

Make a mount point (as a normal user)

Then edit fstab to mount the partition, were I am gonna install win10 in the virtual machine. So probably should format that partition as ntfs, but first I need to make sure, I can point to that partition when installing the vm.
Right now I can’t.

First lets make a back up of the fstab file.

Gps2010 · September 24, 2024, 3:35pm

I am stuck but lets start positive.

I made a mount point and from dolphin I can access /dev/sdb2, without typing the root password.

I do not seem to be able though to use this for the virtual machine I try to install.
The installer wont let me point to /dev/sdb2.

Baby steps forward, but now I get this error when trying to make a new virtual machine:

cannot open directory ‘/var/lib/libvirt/images’:

I do understand that message, but don’t have a clue on how to fix this.

it must be related to this:
