Problem solved by upgrading to 2.6.39 kernel from 2.6.38, at another
server I use 2.6.38 kernel, but there is no such problem
Seems some problem between newer versions of qemu-kvm and kvm kernel
version and also result of fixing KVM: fix kvmclock regression due to
missing clock update

Hello,
I receive strange problem with running FreeBSD guest (7 and 8, x86 and
amd64) on KVM.
When begins boot menu, there is time countdown 10..9..8 etc, and time
between 10 and 9 can be different than 1 sec 0.9, 1.1 etc.
And sometimes countdown hangs on some number.
