Hi,
I just tried the latest Fedora rawhide kernel
(2.6.26-0.115.rc9.git2.fc10.x86_64) in a kvm virtual machine, and I
noticed that it doesn't have all the paravirtual goodness available in
2.6.26. The cost of setting PARAVIRT, PARAVIRT_CLOCK and
PARAVIRT_GUEST to 'y' is suposed to be pretty minimal on bare metal,
and it gives a nice boost running inside kvm. Have you guys
considered turning on these options for Fedora kernels?
Those should be getting set. Except for 64bit, which was broken
a while ago. guess we should retry that.
