Hello, What is the better solution now to run linux domUs under Xen3? Using a VT hardware, sould I install a xen-patched kernel as I would where no VT extension, or use an unmodified linux guest system? Is there any performance difference between a Pentium D 3 Ghz with vt (9xx) and without it (8xx)? Regards, Slapic _______________________________________________ Xen-users mailing list

Hi all, I was wondering if cpu frequency scaling in dom0 (using the cpufreq=dom0-kernel boot parameter) may cause problems with HVM domUs? This is on Xen 3.2.1. PV domUs seem to work just fine. They adjust to the frequency change on the go. The HVM I run using the unmodified_driver drivers (also from the 3.2.1 release) seem to have very slow timers if dom0 lowers the frequency. Birger

Hello group, I recently purchased an HP m7360n computer which has an Intel Pentium D 920 processor in it. Unfortunately there is no BIOS option to enable or disable VT. The board it sits on uses the Intel 945P chipset. If I am in linux and do a ''cat /proc/cpuinfo'' I get this: [root@localhost ia32]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family

After several days of problems, I finally got Xen 3.0.1 set up in Ubuntu Breezy with the 2.6.12 kernel on a VT-enabled system with an Intel 930 processor and 2GB of memory. I have been able to install an unmodified guest without any issues other than performance. The guest runs extremely slowly and the mouse and keyboard are all but useless because of the extreme lag. I''ve tried multiple

Hello, As I saw in this mailing list, there should be some emulation solution for drivers when using VT-x processors. See for example : http://lists.xensource.com/archives/html/xen-devel/2005-12/msg00763.html My question is this; As I understand, the VMX support in the new VT-x processors enables us to prevent Guest OSs from performing unwanted instructions (HLT , for example). This

Hi, Hoping someone can help me with some question on Xen 3.x and Intel VT (Vanderpool) hardware. Can IBM OS/2 or Serenity Systems eComStation now be run with Xen and Intel Vanderpool enabled CPUs? If not, what is needed? Are any drivers needed? Do you know of anyone working on getting Xen to support OS/2 or eComStation? > Jan 21,2004, Mark A. Williamson wrote: > Afraid so. > With

Do you have anything detailing what the goal of each phase in Xenrt is? Phases 4 and 5 seem to be pretty much identical. Thanks, Paul Larson _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, Since a while I am curious to buy a machine with hardware virtualization support. Finally, they start to become available here in Germany. So, I want to get such a machine. I want to buy a dell inspiron 6400 or an IBM thinkpad T60 which are said to have such a mobile processor with hardware virtualization - does anybody have experiences with these? Looking in the Hardware compatibility

Hi Sir, I have a question regarding the security of Xen. What are the security threats in with Intel VT-x.

Hi Can someone help me figure out a way to compile a 2.4 kernel in a 2.6 system. Basically it keeps failing because it needs the genksyms package, which is provided in the modutils package from redhat, but obviously this isn''t presetn on the 2.6 kernel. I was wondering how the xen maintainers go about compiling their 2.4 kernel and 2.6 kernel. Do you do it on different systems then

Hello list Sorry if this is an FAQ but I have just joined the ML\after reading about Xen in a magazine article. I run almost exclusively x86_64 hardware these days and am wondering how x86_64 support is coming along. The article mentions support for x86_64 in V3, due it says this Summer. Are there any developer x86_64 versions available to try yet? Thanks Andrew Walrond

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello folks I played a lot with Xen last days, isnt it possible to access PCI devices which are hidden from dom0? I didnt get it - at least my windows domain didnt get it. Another question: Im using hvmloader but many pages also talk about the vmxloader, was it prior the hvmloader coz it doesnt exist anymore? cheers - -- Georg

I can see that Windows Loads in VM and when I run in safe mode it reaches until loading multi(0)\disk(0)\rdisk(0)\partition(1)\Windows\system32\drivers\Mup.sys After this it hangs.Attached is the qemulog. Note : These VM''s are running out of a complete disk (/dev/sdb), which has working installation of Windows on it! I am running FC5 along with Xen 3.0.2 (tried unstable too) on

I was just wondering what the Xen VT (x86_32 and x86_64) status is at the moment? Thanks, Aravindh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)? >>> On 2008/06/16 at 16:07, Rudi Ahlers <Rudi@SoftDux.com> wrote: Itamar - IspBrasil wrote: > why you''re using hvm ? its slow > > > > Rudi Ahlers wrote: >> Hi all >> >> I''m running CentOS 5.1 x64 + Xen 3.0 & I

Hi everybody, I seen many post on running Windows XP on the top of Xen with proper hardware (Intel Vt) ... I would like to know if at this time, i could do that with Xen 3.0.2-2 or Xen unstable ? If yes, could you tell me the procedure ... In 2 week i will make a show with Intel to demonstrate this possibility ... If at this time we couldn''t, i will change the contents of the show ;)
