Hi folks What are the prequisites to run HVM domains on VT CPUs? I tried it my new ThinkPad X60s with a Core Duo (Yonah), Intel 82801G and Intel 945GM. I used changeset 9602 of the xen-3.0-testing repository for the tools and changeset 9610 for the kernel. After the creation of the domain, the whole system lookups hard and I can''t even ping it any more.

Hello, I''ve had the same type of experience on Intel 945 with D920 cpu. Turning off acpi and apic in the xenU helped a bit ... but anyways I found it too unstable for anything than playing around.

RE: [Xen-users] prequisites to hvm domains on vt cpus
HVM is still new in Xen, so the unstable changesets are going to be pretty variable as to what works and what''s broken. I think it''s fair to say that you need to PICK CAREFULLY to find a really good changeset. Check the Xen devel mailing list for test-results to see if there is a recent changeset that looks more hopefull. But certainly here at AMD, we''re still fixing things in SVM-code, and I''ve only recently fixed some bugs that were in shared HVM-code, and I don''t think those are the last ever bugs to be found. ACPI can certainly make things worse, but I think the APIC emulation is decent right now (although I may be wrong on that). What type of domain did you try? Windows, Linux or something else? Did you have a serial console attached, and if so, did you see anything printed that may give a clue to what went wrong? -- Mats> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of > Tomas Florian > Sent: 13 April 2006 16:15 > To: Bastian Blank > Cc: xen-users@lists.xensource.com > Subject: Re: [Xen-users] prequisites to hvm domains on vt cpus > > Hello, > > I''ve had the same type of experience on Intel 945 with D920 cpu. > Turning off acpi and apic in the xenU helped a bit ... but > anyways I found it too unstable for anything than playing around. > > Tomas > > Bastian Blank wrote: > > Hi folks > > > > What are the prequisites to run HVM domains on VT CPUs? > > > > I tried it my new ThinkPad X60s with a Core Duo (Yonah), > Intel 82801G > > and Intel 945GM.

I was expirencing some hard lock ups too but after changing to xen 3.0.2 and installing: dev86, libvncserver, and the SDL libraries everything ran very smoothly. -Dan On 4/13/06, Petersson, Mats <Mats.Petersson@amd.com> wrote:> > HVM is still new in Xen, so the unstable changesets are going to be > pretty variable as to what works and what''s broken.

This is a serious problem, as it blocks SIGCHLD. - Don''t use file as backend for storage. lvm does not create any lookups. The linux kernel within the domain locked up within the video output a short time later. It uses the vga framebuffer.
