Description scientes-bugs+redhat-a1fff8cf024e022a6ab3 2009-05-08 15:32:26 EDT
Description of problem:
I have a server that doesnt have VT/AMD-V extensions. Xen would be overkill. I noticed that in version ~0.5 there was a kqemu option but it is no longer available for local or remote domains. when choosing qemu it sends -no-kqemu as a parameter making kqemu not run. kqemu is alot faster than qemu.

Version-Release number of selected component (if applicable):
virt-manager: 0.7.0
libvirt (local): 0.6.1
libvirt (remote, without virt extentions): 0.4.0

both hosts have kqemu installed, built and loaded 

How reproducible:

Steps to Reproduce:
1. get to step 5 of new VM walkthrough
Actual results:

2. no kqemu under "Virt Type"
3. when a qemu instance is run -no-qemu can be seen via 'ps'

Expected results:

2.some way to run kqemu
Comment 1 Cole Robinson 2009-05-09 18:59:14 EDT
Is there a kqemu rpm installed, or is it installed by hand? If by rpm, please include the output of 'rpm -ql kqemu'.

Also, provide the output of:

virsh capabilities
ls /dev/k*
Comment 2 scientes-bugs+redhat-a1fff8cf024e022a6ab3 2009-05-31 05:30:12 EDT
For outputs see #499056.
Comment 3 Cole Robinson 2009-06-15 14:16:39 EDT
According to your capabilities output, libvirt isn't finding kqemu, therefore virt-manager doesn't list it as an install option. But your 'ls' output shows /dev/kqemu.

Does 'service libvirtd restart' change the output of 'virsh capabilities | grep kqemu' ?

Re-assigning to libvirt.

Can you confirm Cole's question from comment #3.
