 |
|
I run Gentoo on my host and in my guest VM.
In the Guest i have install und run xf86-video-qxl and qemu-guest-agent.
I start Qemu with:
| Code: | /usr/bin/qemu-system-x86_64 \
-M pc-q35-2.4 \
-cpu host \
-machine accel=kvm \
-smp 4 \
-m 4096 \
-name __vm82__ \
-k de \
-rtc base=localtime \
-drive file=vm82_disk.qed,id=drive-sata0-0-2 \
-realtime mlock=off \
-net nic,model=virtio,macaddr=00:00:00:00:00:82 \
-net tap,ifname=qtap82,script=no,downscript=no \
-vga qxl \
-device qxl,id=video0,ram_size_mb=256,vram_size_mb=256,vgamem_mb=512 \
-spice port=5901,addr=127.0.0.1,disable-ticketing,image-compression=off,jpeg-wan-compression=never,streaming-video=off,zlib-glz-wan-compression=never \
-device virtio-serial-pci \
-device virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 \
-chardev spicevmc,id=spicechannel0,name=vdagent \
-usbdevice tablet \

With spicy or remote-viewer i connect to the VM.
The VM runs in KDE often very very slow. I the X.org-Logfiles i see a lot of "out of surfaces" messages.
If i start Firefox the VM runs more slowly and the "out of surfaces" messages comes 10 a second or so.
Whats wrong here?
How can i fix this problem? |

Do you have a configuration file for X?
If not create a file named 20-qxl.conf containing
| Code: | Section "Device"
Identifier "qxl"
Driver "qxl"
Option "DPI" "96 x 96"
Option "ENABLE_IMAGE_CACHE" "True"
Option "ENABLE_FALLBACK_CACHE" "False"
Option "ENABLE_SURFACES" "False"
EndSection |
and put into your /etc/X11/xorg.conf.d/ directory of your Gentoo guest system
This should speed up things but don't expect any miracles. |

Glad you got it working.
I really can't remember where I got the information from, but I do recall that it took a while to find it.
By the way, after looking at your initial post again, I noticed that you didn't mention installing spice-vdagent on your guest system. If you haven't done so already I'd recommend you to install it and add it to your default runlevel, since it's apparently needed for certain spice features to work.
On the other hand, I don't think that qemu-guest-agent is absolutely necessary to run a KVM guest with spice. |

That's supposed to be a functionality that you'll get by installing spice-vdagent on your guest system.
However, I can't properly test it with my own setup since I'm using a tiling window manager on the host system. |
