KVM on Fedora

DustinB3403

So I'm trying to get this going, and I'm starting to get irritated.

I've installed KVM, it runs fine. I create a VM using a local ISO on the default SR available. I create a new SR using the remaining 900something GB of space and then create a qcow2.

I use this qcow2 as the disk for the VM, and install. The install completed. I shutdown the VM, reboot the host and then the qcow2 is missing.

WTF?!

Paging @scottalanmiller for guidance.

@dustinb3403 usually, the problem is the LV not mounted at boot time. Check your fstab, try to mount the LV manually etc.

This is what I've got.

I've just added

/home/user.name/vm-storage/ defaults 1 1

to fstab, should that do?

And actually looking in the existing directories that I was going to use, nothing was there. .

Is your new storage set to autostart on boot?
Check the connection details for storage.

DustinB3403

@black3dynamite at the VM level or host?

black3dynamite

@dustinb3403 From the host.

DustinB3403

This is my first swing at kvm so treat me like a toddler.

I would assume if I create a file using virtmanager that it stays between hosts reboots...

DustinB3403

Hrm for whatever reason it stayed this time...

black3dynamite

What do you have set up for your storage?
The state status should be active and autostart on boot enabled.

Why didn't you set this up before you installed Fedora using custom partitioning?

Now, why aren't you fixing it via Cockpit?

DustinB3403

@black3dynamite It is, and was set to that as well.

black3dynamite

Did you create the vm under qemu:///system or qemu:///session (user session)?
