Category: intel Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Rafal Wijata (ravpl) Assigned to: Nobody/Anonymous (nobody) Summary: gettimeofday goes backward Initial Comment: kvm version: 71 host: rhel51 2.6.18-92.1.6.el5 64bit 16G RAM, 8CPU guest: rhel51 2.6.18-92.1.6.el5 64bit, 3.5G ram, 2 CPU guest run as: qemu-system-x86_64 $DEVICES -m $MEM -smp $CPUS -net nic,macaddr=$MAC,model=e1000 -net tap,script=./ifup -nographic -daemonize in the guest executed two consecutive gettimeofday (boost::ptime in fact), the latter returned time smaller than first (2008-Jul-22 16:34:15.477000, 2008-Jul-22 16:34:15.470000) I'm sure no time change was made(like rdate or ntpdate) on neither host or guest. No time-releated options were passed to kernel(host or guest) Any workaround? ---------------------------------------------------------------------- >Comment By: Jes Sorensen (jessorensen) Date: 2010-08-19 12:24 Message: Hi Trying to catch up on the old bugs. Do you still experience this problem with a current version of KVM? The problem should be resolved in upstream, in particular if you run with kvmclock. Would you please close this bug if the problem is no longer there?
