Hello List, I am new to this list, but not to Xen. I successfully use Xen for 1 year now and 2 weeks ago I decided that it''s time to get new hardware, that supports HVM guests. So far so good. Now I am a more or less happy owner of a AMD AM2 X2 3600+ X2, a GA-M61P-S3 and 4GB DDR2-800. The problem is that I don''t get the HVM guests to work: cat /proc/cpuinfo |grep -i svm flags: [...] svm [...] looks like my CPU supports AMD-V, right? xm create winxp Using config file "/etc/xen/winxp". Error: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS? So, lets take a closer look at that! xm dmesg |grep -i svm (XEN) AMD SVM Extension is disabled in BIOS. (XEN) AMD SVM Extension is disabled in BIOS. Hey, what''s that?? Why is it disabled?? I checked the BIOS and even with the CTRL+F1(extended Bios-Options) I don''t see anything related to "virtualization support". Am I just stupid/blind?? Are there Mainboards on the market, that claim to be AM2-compliant but don''t support Virtualization?? If you have any ideas what this could be, please tell me. Greetz Age_M PS: I installed Xen 3.0.4.1 on top of Gentoo 2007.0 in x86 not x86_64! PPS: Linux guest working fine here! -- Ist Ihr Browser Vista-kompatibel?

It''s possible a bios upgrade will reenable the option. Which motherboard is it?

Hi Tony, first of all, thanks for your reply. The mainboard is a Gigabyte M61P-S3 with a Nvidia nforce430 chipset (+ onboard GeForce6100 VGA). Regarding the bios, it''s already the latest version F4 :-/ I also already contacted Gigabytes tech-support, but have no reply yet. Damn, that''s totaly pointless when manufactures ignore given specifications. The only reason I switched to AM2 was/is HVM support. Is there any way to override such a problem? Sometimes the kernel just ignores Bios-Options, so is there parameter to fix this, or do I have to wait until either Gigabyte releases a new bios-version with the wanted option available or until I buy a new mainboard!?

On my P35C-DS3R there''s an option in the advanced bios settings called ''Virtualisation Technology'', which defaults to on.

Hello Mats, I think I didn''t really get the point in your statement. "please wait until the processors are available" What processors are you talking about?! My AMD AM2 3600+ X2 (65nm) already has the AMD-V feature, right?!? And the Mainboard already has turned off this AMD-V feature, but I want to turn it ON again, right?! So, what do I have to do to get HVM support? New CPU? New Mainboard?? Or should I completely switch to Intel Core2Duo? I am completely irritated now :-p Greetz Holger Petersson, Mats wrote:> > > >> -----Original Message----- >> From: xen-users-bounces@lists.xensource.com >> [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of >> Christian Horn >> Sent: 07 June 2007 09:14 >> To: Tony Hoyle >> Cc: xen-users@lists.xensource.com >> Subject: Re: [Xen-users] Xen 3.0.4.1 AMD-V HVM >> >> On Wed, Jun 06, 2007 at 08:02:38PM +0100, Tony Hoyle wrote: >> >>> Yes.

Hi again Tony, thanks anyway :-D I tested 2 bios-versions and both don''t have this option. so, it seems that I have only one choice left: buy new hardware once more...

Hi there again ;) Thanks for the reply, I think I get it now. So the only problem is the Mainboard. Do you think I am in a position to expect Gigabyte to fix this? Is it my right to say "This is an AM2 mainboard, so you have to build this feature into the bios?". I mean, virtualization is a key feature of AM2, right? I really hope, that I don''t have to buy a new mainboard again :-/ Thanks for your detailed explanations ;) Greetz Holger Petersson, Mats schrieb:> > > >> -----Original Message----- >> From: xen-users-bounces@lists.xensource.com >> [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Holger >> Sent: 07 June 2007 14:30 >> To: xen-users@lists.xensource.com >> Subject: Re: [Xen-users] Xen 3.0.4.1 AMD-V HVM >> >> Hello Mats, >> >> I think I didn''t really get the point in your statement. >> >> "please wait until the processors are available" >> > > This was in reference to the NEW processors that are not yet on the > market - I can''t really tell the general public about details of > processors that are not yet available - at least not if I want to > continue working for AMD... > >> What processors are you talking about?!

Is it my right to say "This is an AM2 mainboard, so you have to > build this feature into the bios?". I mean, virtualization is a key > feature of AM2, right?Well, the KEY feature to processors that go into an AM2 is the ability to use DDR2 memory (which for the same performance is less expensive than DDR). It just so happens that we (AMD) choose to implement virtualization features into the same product upgrade cycle, so AM2 is an easy way to explain which processors have AMD-V or not. And the other key point here is that before Rev G, it was very difficult to disable AMD-V. In Rev G, it''s one bit which is "sticky" (sticky means that it can''t be reset without resetting the entire processor) in one register to disable AMD-V. There is ABSOLUTELY no reason why this shouldn''t be fixable in the BIOS.> I really hope, that I don''t have to buy a new mainboard again :-/Yes, I agree - although I would also say that if you bought the system with the intention of running AMD-V, then it would be fair to say that you should be able to take the motherboard back to the shop with a complaint that "it doesn''t do what it should be able to" based on not being able to run AMD-V. [Being stricly legal, this is possibly beyond what the legal definition of "fit for purpose" covers if you didn''t explicitly say to the retailer that you NEED the AMD-V feature - but I still would attempt to get a replacement it on these grounds before just buying a new motherboard]. -- Mats> > Thanks for your detailed explanations ;) > Greetz Holger > > Petersson, Mats schrieb: > > > > > > > >> -----Original Message----- > >> From: xen-users-bounces@lists.xensource.com > >> [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Holger > >> Sent: 07 June 2007 14:30 > >> To: xen-users@lists.xensource.com > >> Subject: Re: [Xen-users] Xen 3.0.4.1 AMD-V HVM > >> > >> Hello Mats, > >> > >> I think I didn''t really get the point in your statement. > >> > >> "please wait until the processors are available" > >> > > > > This was in reference to the NEW processors that are not yet on the > > market - I can''t really tell the general public about details of > > processors that are not yet available - at least not if I want to > > continue working for AMD... > > > >> What processors are you talking about?!

Hi there :-D I don''t believe it. your explanation brought me up to an idea! if the g stepping cpu is the first cpu that support deactivation of AMD-V, what would happen if i use a bios version that doesn'' recognize the G-step cpu :-p voila.. bios version F2 activates the AMD-V feature -> I don''t believe it. I am just worrying what would happen to my system!? turning off speedstepping should do it, right?

Hi Nico, yes, this would be great, even though I am no programmer, so I hardly could fix things myself :-p But look @the other thread. I did it :-p I fixed the problem with flashing an old bios version, that doesn''t recognize my cpu :-p Greetz Holger Nico Kadel-Garcia schrieb:> Holger wrote: >> Hi again Tony, >> >> thanks anyway :-D I tested 2 bios-versions and both don''t have this >> option. so, it seems that I have only one choice left: buy new >> hardware once more... >> >> Greetz Holger > Heh.

Can you try running Xen 3.1 with the newer BIOS and see if says "AMD-V locked by BIOS" when you attempt that?

Hi again, actually I still have the Xen 3.0.4.1 version installed. But I have seen some ebuilds(using Gentoo) for xen 3.1 Will try to install, maybe today (having some minor network problems with e1000), but AMD-V in xen-3.0.4.1 looks quite fine.
