Hi, c/s 20194:582970a2d2dc overloads the system. [BEFORE] $ time xm create hvm.cfg memory=1024 Using config file "./hvm.cfg". Started domain hvm (id=3) real 0m2.343s user 0m0.040s sys 0m0.030s [AFTER] $ time xm create hvm.cfg memory=1024 Using config file "./hvm.cfg". Started domain hvm (id=2) real 2m25.741s user 0m0.090s sys 0m0.020s I'm about to lose my patience with it. :-) Can you control it by a boot parameter? (ex. "pod_debug=nnn") Thanks, Kouya George Dunlap writes: > The PoD code assumes that if: > * A page is in a domain's p2m table > * And it's owned by the domain > * And it's not a xenheap page > then: > * It's on the domain's page list. > > This patch adds a check for this assumption when debug=y. > > Signed-off-by: George Dunlap <george.dunlap@xxxxxxxxxxxxx> _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
