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

You need to add dom0_mem=XXXm to xen or scale back the memory of domain0 with using "xm mem-set <DomId> <Mem>" command. Your domain0 used up almost all physical mem. >total_memory : 1023 >free_memory : 62 Thanks Yunfeng >-----Original Message----- >From: xen-devel-bounces@lists.xensource.com

Hi, I''ve recently setup a few machines with 3.2 64bit without any unresolvable problem. These machines all run pv domU''s and a view "basic" hvm domUs. As I''ve got one machine left for internal use and testing, I would like to take a look at pciback with VT-d support (bios screen shows a VT-d [enable|disable]). My question is, do I need to add patches, or use

I've set up a local webserver to store kickstart files for domUs. All parameters are respected apart from the network settings. DomU always gets DHCP. Can any one help to unwrap this one? Does one add hostname, ip, netmask and gateway values to the /etc/xen/blah.cfg file? # ---- domU kickstart file ----# url --url http://192.168.1.120/centos/5/os/i386 lang en_US.UTF-8 keyboard uk network

help Hi guys, For Xen 3.0.1 is it possible to run 32/64 bit SMP VT enabled guest? What is the main difference between vcpus and cpus options in the guest config file?

Just wondering if there was a howto or other URL that explains what is needed to achieve "near native" performance on a xen domU -- for this purpose, I am thinking about a single domU running on a physical server, in comparison to that same physical server running the same kernel but non-xenified. For instance, using a physical partition for VBD v. using a file-backed one is one

Hi, For each domUs there is unique shared memory(2-way circular queue) and event-channel(one shared memory and event-channel per domU) or there is only one shared memory and interdomain event-channel(for every DomU)? regards: Amit _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Chaps, Perhaps this question is a little basic for this list but I''m not really sure of the simplest method or best tool for the job. I''ve created some images with `dd=/dev/zero ....` and I''m using them for the domUs now. Some of them have been running for a few months with no probs. Trouble is that I''d like to create a separate partition within the domU.

Hi list, I''m using Dom0 gentoo with xen 3.0.4 and xenman. I have several DomU working and it is really nice :) so all my DomUs are installed with disk images. Now i want to use an ISO to boot and install a linux system (or win). When i try to boot the DomU i dont have nothing, nothing relevant (for me) in logs and i can connect to the console. The state of the DomU is unknow. Any help

Hi all! I''m hoping someone here might be able to help. I''m familiar with several UNIX''es, though farily new to Linux... I''m running RHEL 5.2. I''ve got the RHEL kernel headers installed, etc, and compiled xen-3.3. Once that was built, I rebuilt libvirt, etc, the kernel, and all the modules. The whole mess boots and runs fine... mostly. My hardware

Hi, I really need help. I spent 2 days already on this pci passthrough thing. I''m using Xen 3.2.1 with Centos 5.2 64 bits on intel VT. I''d like to use PCI passthrough and I don''t think I need VT-D functionality. I''m trying to pass PCI 12:01.0 to my domU guest. I got this error when I use "xm create /etc/xen/hvm_centos_2.cfg" Using config file

Hello there, I am using a Gigabyte H55M-UD2H (Intel H55-Chipset) together with a Core-i5-650. According to Gigabyte Support the Mainboard does support VT-d. Well, actually support says, that VT-d does work on Windows-7 in XP-Mode. They do not test and support Linux though. Did anybody here have success using VT-d on any H55-Board? Perhaps it is some misconfiguration on my side. I tried a

All, We are facing some issues bringing up a DomVT on Xen x86_64(changeset 9267). We created a disk image with dd 8 G in size. We then booted an associated Dom-VT with a CD-ROM and did net-install of the sles-9 OS. This completes successfully. Then, when the system is brought around for a reboot (having changed the boot option from cdrom to disk), the system hangs after the line

Hello all, I know that the question: Is it possible to run quemu inside Xen domU or run Xen domain 0 on quemu have discussed earlier in this mail list. As far as I remember this is possible except such a configuration where kquemu acceleration is in use. But what about HVM-capable systems? Please tell me are there the same restrictions for the hvm-capable systems? Thank you! -- WBR,

Can I run 8/07 fully virtualised on an Intel VT CPU (with a Linux Dom0)? I gave up on 11/06 because of real mode problems. If not, does anyone have an estimate of when this might be possible, if at all? Thanks - Evan

Success story: I''m now successfully running WinXP Home Edition as DomU under XEN, with Gentoo Linux dom0.

(Despite predictions elsewhere on this mailing list, the P965 _does_ seem to work just fine for VT. The

Hello, I have been working sometime now on getting a HVM accepting a PCI card from the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO motherboard (rel 0803) which has the VT-D option in the bios. I want to pass a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After first trying XEN 3.2.1 which did not enable the "VT-D virtualisation" bit in xm dmesg, i

Hello I have Debian Linux 2.6.32-5-xen-amd64 Xen 4.0.1, 2 SAS drives in RAID 1, 16GB ram. I have virtualized Windows 2003R2 32bit where you install the latest version 0.11.0.295 gplpv After reading and reading forums and post testing, I noticed that the hard disk performance drops significantly when I assign the windows domU 9GB ram.
