[Xen-devel] Xen 4.0.0 rc7 xen_safe_halt

["IPvE.COM vLan Service" <svc@xxxxxxxx>]

Dear,

I installed xen 4.0.0 rc7 to my server and create one virtual pc for windows 
xp. The server config is Intel E6500 + Intel Q45(DQ45CB), I pass the vga and 
audio to the virtual pc, when I install the game in the windows xp, sometime 
the virtual pc and dom0 hang, event can't ping the dom0 ip at all. but after 
few minutes, it continue to working...

I ssh to the dom0, found some log at syslog below:
