Hi there, After installing Spice on Ubuntu Quantal Quetzal
and setting up a Win7 host with the QXL drivers (which are found correctly),
things aren’t working as they should. The performance of the graphical
layer isn’t optimal. There are three issues I found: ·
When stressing the VM by
playing a full hd movie, the CPU of the guest OS tops at 100% and the
performance is reduced massively ·
I get quite a few warnings on
the Hypervisor saying: (/usr/bin/kvm-spice:3756):
Spice-Warning **: red_parse_qxl.c:406:red_get_image: guest error: missing
palette on bitmap format=2 ·
When adding the Audio driver to
the command line to run the guest, video performance of the guest is completely
gone when stressing it by playing any kind of video. The audio is working
correctly, but the video performance is drastically reduces. The command for
this: kvm-spice … -device AC97,id=sound0,bus=pci.0,addr=0x5 The command I use to start the Windows 7
guest: kvm-spice -cpu host -name win-7 -enable-kvm -m 3000 -M pc-1.2 -net
nic,macaddr=DE:AD:BE:EF:95:D0 -net tap,script=/etc/qemu-ifup -usb -drive
file=/var/vmmachines/win-7.img -vga qxl -spice port=5901,disable-ticketing I used Ubuntu 12.10 server (Beta 2) as
hypervisor, the server is able to support hardware acceleration. To install all
tools, I ran apt-get install qemu-kvm-spice QEMU emulator version 1.2.0 I’m basically stuck with proving the
capabilities of SPICE, which I know are amazing, but I can’t get it to
work properly. Kind regards, Tom |
