I got latest (13601) yesterday evening. This doesn''t seem to work to do Restore (at least of the Windows test-image that I''ve been using for testing previously). The VM restores reasonably OK, but it jumps to an invalid address shortly after restoring, giving a D1 blue-screen error (DRIVER_IRQL_LESS_OR_EQUAL), which turns out to be "page-fault in driver" after I looked at the memory dump in windbg. (The address it jumps to is consistenly a0000ca5, if that''s of any meaning to anyone). I''ve compared my svm.c that I had previously and the current one that I got from mercurial, and they are identical. I went back to my 13568 build of the hypervisor, and it works there... There''s no obvious changes in between... Has anyone else tried this, does anyone have an idea of what''s going wrong? -- Mats _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Mats, at least 32b up windows on 32b HV save/restore works here. what''s your configuration? 32 or 64 windows/HV? up or smp? BTW, can you have a try with linux guest?

I tried suspend/resume with a Linux guest with 1 processor.
I get the following errors in xend''s log file upon resume.
