Hi, I am currently trying to create a DomU to run an unmodified Linux Distro Installer from CD. So far I have managed to get Xen 3.0.3 running on Debian Etch and I have created a configuration to run the installer in a new virtual machine. Now whenever I try to create the virtual machine with "xm create" I get the following error message: Error: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS? OK. This error message is rather obvious and actually the first time it was right, VT was disabled in the BIOS, so I went and enabled VT in the BIOS, but still when I try to create the virtual machine I get this error message. Can anybody give me some hint as to why Xen will not recognize VT support? Do I have to recompile xen after enabling VT in the BIOS? Or is the Xeon 5130 just not supported in Xen 3.0.3 yet? Thanks a lot in advance Ralph _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Actually I managed to get everything working as expected on my computer at home which has a similar CPU, so I am going to repeat all the steps on this server and hope for the best. I guess there is some issue with the Debian packages, although I don''t have a clue what it is.

Hi again, it took me a while to resetup the whole machine since the integrated network interfaces are not supported in kernel 2.6.16. But now the whole thing is up again, but it still shows the same problem. Xen is basically telling me that the CPU does not support VT or that it is not enabled in the BIOS. But I did enable it in the BIOS and /proc/cpuinfo show that the vmx feature is present in all four CPUs. I am somewhat puzzled since it works on my Core2 Duo at home without problems. Maybe someone else has had similar problems and can point me to where I did something wrong.

OK. Last mail hopefully. Somehow I solved the problem or rather the problem solved itself and I don''t really understand it. I downloaded a processor identification tool from intel which confirmed that the processors do have the VT extension just to be sure. I also downloaded a live CD with 3.0.3 on it. Since the one from the Xen downloads always stopped downloading after 1M, I got a Xennopix DVD which also features Xen 3.0.3. I booted from the DVD and ran one of my configurations which had always failed so far and it worked. Next I rebooted into Debian on the Server again and started the same configuration and it suddenly also worked. I have absolutely no clue why this should be the case, but there it is. I have rebootet this machine at least 20 times today and tried to run the configuration at least 10 times and it failed each time telling me that VT was not available and all of a sudden it works without me changing anything. I guess I will just have to accept it and I am glad it works, but I really wish I could understand this.
