Virtual Manager (virt-manager) and kqemu

[SGSeries2]

I didn't really see this elsewhere, so I figured I'd post my findings if someone else was wondering what was up.

Some people may be wondering about that little kernel/hardware acceleration checkbox on the third page of creating a new 'fully virtualized' machine in virtual manager's new machine wizard, and why it is greyed out. That is the way I found it by default at least on my 64-bit version of Sabayon 3.5.

I installed kqemu, did a modprobe kqemu, and the checkbox became available. I used to use virt-manager "back in the day", and I did notice a speed increase when kernel/hardware acceleration was enabled. Qemulator and Virtualbox 1.6 are pretty cool, too.

Anyways, this was with libvirt 0.3.3 & virt-manager 0.5.0.

Just FYI for anyone who's looking into using virt-manager.

Maybe you could put a "how to" on the wiki?

Can you gently help me ?
I said you installed kqemu...

...and I also tried...but without results...

I tell you which steps i took:

emerge-webrsync (I'm under uni. proxy)

emerge qemulator ... ERROR gcc compiler 3.xxx needed

equo install gcc 3.xxx
gcc-config gcc 3.xxx
source etc profile

emerge qemulator ... OK ... installed also qemu (as I thought...but I also thought it will install kqemu... )

emerge kqemu ERROR ...

tatonezabayone carota # emerge kqemu

I tryed with both compilers gcc4 and gcc3 but with no results...

Since you still haven't figured out about pasting in the IRC channel, or what needs to be done as root,
eselect kernel set 1 must be done as root, not user.
