FWIW, I just started Xfce with xfwm4 and using firefox played a live-stream of 
Taiwan News on YouTube
and the audio/video sync was good fine. I also stream a John Oliver Last Week 
Tonight segment and it
was also good. The video was 16 minutes long and lips/audio were 99% fine.  A 
little blip here and there
but is recovered.   Surprised the heck out of me.  :-)

Never mind

If one logs in from multi-user mode and does startxfce you get that window 
manager.

I've not seen any crashes on my VM.  Host is F34 and multiple guests, including 
F34 guests.

As a test, have you tried changing your guest video from QXL to Virtio?


Worth a try. I am now running with Virtio video. Audio sync is a bit out...

Interestingly: I tried to change back to QXL for comparo but LXD could not 
start,
X repeatedly terminated with
[    43.747] resizing primary to 3840x2160
[    43.747] primary is 0x5640e09faa30
[    43.747] (EE) qxl(0): failed to set mode: Cannot allocate memory(EE)
I will deal with this later.



Is your host running low on memory?


I do not think so. I changed back to QXL and LXDM failed in a loop, at that 
point
I did this on the host:

$ free
   total    used    free  shared buff/cache   available
Mem:    32734592 3232096 7343812  246400 22158684    28782264
Swap:   16777212 1064704    15712508

The guest is configured with 8GB memory.

[later] I had a very vague memory that I needed to fiddle with the domain xml 
file.
I restored /etc/libvirt/qemu/e4.xml from backup and compared and sure it was 
different.

I used
$ sudo virsh edit e4
and set the  stanza to say

where it originally said

Now lxdm starts OK.

Audio sync still bad. Video barely keeps up. Probably similar to virtio mode.

I will run this way until I get an Xorg crash, then switch to virtio to see if 
it is better.



OK   I forgot to ask.  This is F34 installed from what Live Image?


This system was installed too many years ago to remember and upgraded every 
year.



I see.  What desktop and display manager?


xfce4 xfwm4



Oh, I can't seem to find xfwm4 display manager available for F34.

What is the outupt of

I've not seen any crashes on my VM.  Host is F34 and multiple guests, including 
F34 guests.

As a test, have you tried changing your guest video from QXL to Virtio?

Xorg crashes in KVM

2021-07-09 Thread Eyal Lebedinsky

Recently I started having Xorg crash while using firefox.
This is f34 in a libvirt kvm, host (also f34) uses internal i915 video.
Kernel is 5.12.14-300.fc34.x86_64 but saw this with earlier 5.12.12/13 kernels.

an example crash:
