Still getting a misbehaving clock:
guest uses kvmclock with kernel 2.6.27
host kernel is 2.6.27 with kvm-qemu-87 & kvm-kmod-87
doing:
now = gettimeofday
goal = now + 10 minutes
while (now < goal) {
sleep(10)
now = gettimeofday
print(now)
}
getting:
...
now = 2098031895
now = 2108035868
now = 2118039818
now = 2128043797
now = 2138048010
now = 18446744071562636328
Thanks very much,
Eran
