Hi all, I''ve recently installed xen-linux-system-2.6.18-6-xen-686 on debian/testing. Running the stock debian kernel, the /proc/cpuinfo file shows svm flags (I want to use HVM), but when I boot using xen kernel, the flags are not present. The processor is an AMD AthlonX2 64bits, and is listed as processor that support HVM. Is it possible that the xen kernel doesn''t have this flags available? I''m running debian/testing i386 and would like to run winxp on a xen domU. regards, -- edu _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

That is unexpected though to me, but someone else had a similar problem with an AMD system on etch and built their own from source: http://www.math.dartmouth.edu/~sarunas/xen_304_hvm_etch.html You could try grabbing a more recent xen.org kernel to test.

I suppose that''s normal. I''m using 3.2 xen hypervisor and vms nor vmx flags come up in /proc/cpuinfo. The dom0 is a 2.6.18 kernel, maybe that''s the reason. hvm works just fine - I''m running windows XP domU''s. Kindest regards, Peter.

Check for the following output in the xm dmesg command: (XEN) AMD SVM: ASIDs enabled.

Or, use the "xm info" command and look for "hvm" mentioned in the xen_caps field.
