permission error KVM

English Virtualization
1

I’m trying to install virtual machine on KVM.
I get this error at the begging of installation process.

Unable to complete install: 'internal error: qemu unexpectedly closed the monitor: Failed to create //.cache for shader cache (Permission denied)---disabling.'

if I deselect OpenGL this would eliminate the error, but without OpenGL graphic acceleration on VM is terrible.

Try this hail mary try and create the cache file ahead of time

touch //.cache

Then test to see if your problem is solved.

A FYI -
There have been a few Forum threads recently that relate to libnetcontrol.

Here is an older one,
https://forums.opensuse.org/showthread.php/534601-network-connectivity-problem?highlight=libnetcontrol

There is another one this past week I’m having problems locating, IIRC it related to his installing (or not installing early on recommendation and having to create a br0 later by other means) and then needing to configure in YaST properly.

I’d have to ask you the same question I asked in that other thread…
Did you install your KVM, libvirt and create a bridge bridging device (br0) using the YaST “Install Hypervisor and Tools” or did you install by picking out packages or a pattern in YaST Software Manager or zypper?

Hi
This of course assumes the OP has multiple ethernet adapters as well, hopefully they do :wink:

I have several eth ports. I used YaST for creating KVM and libvirt. br0 was there actually when I wanted to created it on network management, so I did not add br0 when I created KVM. However, that was a problem to set KVM with br0, so I just left it behind to test OpenGL.
I can rollback to the first stage. is that useful? do you have any recommendation to create KVM with Zypper or again YaST? or anything else?
