The following patches are the latest update of the TSC and hrtimer patches I posted on 29/03. Rusty's original TSC patch has been resynced to the latest lguest repo, as has the hrtimer patch, which also incorporates feedback from Jeremy & Rusty: - Change clock event hrtimer to absolute time.

Hi, I find PV domin hung, When we take those steps 1, save PV domain 2, change system time of PV domain back 3, restore a PV domain or 1, migrate a PV domain from Machine A to Machine B 2, the system time of Machine B is slower than Machine A. the problem is wc_sec will be change when system-time chanaged in dom0 or restore in a

Hi to all, I'm trying to run Battery3 with Wine, but I'm experiencing some problems. 1. When I launch Battery (command line) I see these messages: --- fixme:win:RegisterDeviceNotificationW (hwnd=0x50062, filter=0x32fcb0,flags=0x00000004) returns a fake device notification handle!

Hello all, I'm new to the list, and hoping someone can point me in the right direction. I've got an Ubuntu 14 dom0 with, what I think, are excellent specs. 12 cores, hyperthreaded, VT, 64GB RAM, gobs of disk, etc... all to run 8 virtual machines (at the moment). My problem is each of the guests - Windows, Ubuntu, FreeBSD, starts out working fine. After several minutes, the guest
