Do we need this patch, with the new qemu-kvm patch ?
----- Mail original ----- De: "Wolfgang Link" <[email protected]> À: "pve-devel" <[email protected]> Envoyé: Vendredi 16 Septembre 2016 13:14:51 Objet: [pve-devel] [PATCH qemu-server] fix Bug #615 Windows guests suddenly hangs after couple times of migration Windows has a clock/tick problem when it is live-migrated. This problem ends in a pseudo freeze status. The solution is to stop the clock, when we suspend the VM for live-migration. see man kvm -rtc clock=vm The drawback is the VM will lose a little time on every live migration. So with this setting it is recommended to have a time-sync client in the VM to keep the time. --- PVE/QemuServer.pm | 1 + 1 file changed, 1 insertion(+) diff --git a/PVE/QemuServer.pm b/PVE/QemuServer.pm index dbd85a0..d3eeac5 100644 --- a/PVE/QemuServer.pm +++ b/PVE/QemuServer.pm @@ -3002,6 +3002,7 @@ sub config_to_command { $ostype eq 'wvista') { push @$globalFlags, 'kvm-pit.lost_tick_policy=discard'; push @$cmd, '-no-hpet'; + push @$rtcFlags, 'clock=vm'; if (qemu_machine_feature_enabled ($machine_type, $kvmver, 2, 3)) { push @$cpuFlags , 'hv_spinlocks=0x1fff' if !$nokvm; push @$cpuFlags , 'hv_vapic' if !$nokvm; -- 2.1.4 _______________________________________________ pve-devel mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel _______________________________________________ pve-devel mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
