Changeset 21433 [Re: [Xen-devel] Biweekly VMX status report. Xen: #2143
I am seeing xen hang/freeze when trying to create (hvm) DomU. I have
narrowed down the offending changeset to 21433.
Also, the bug appears only if the host is running in MP mode (UP works
fine .. by changing bios settings). Preliminary evidence points to
some missing vmx initializaiton with MP. I will be doing further
analysis tomorrow. But, is anyone else having a problem because of the
changeset too ?
