similar to: help VT SMP guest question

Chaps, I finally have access to a VT enabled box. What would be the best way to get the most out of Xen and VT? A number of questions here. Bear with me. They may seem simple but all I did previously was get the source code, study it a bit, read the README and build from source. Now that I have a dual-core machine how does Xen know how to split resources for the instances? Does one give any

I have a self built system using an Intel D 920 processor and a MB that supports VT. I''m able to run HVM domains fine, but have trouble getting multiple VCPUs for these domains. Here is an example of one of my configs. # -*- mode: python; -*- #============================================================================ # Python configuration setup for ''xm create''. #

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

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

Xen 3.0 is supposed to support Intel VT (Vanderpool) hardware. I can not find any place that has these Intel CPUs or systems. Anyone know where to get Intel VT (Vanderpool) CPUs or systems? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

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 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

Hi, I''m working with Xen 3.0.1 and I have the following problem: I''m running Xen in a VT enabled Intel processor, I have successful installed a Fedora Core 4 32 bits Guest using VT. But the Network interface doesn''t appear in the Guest. I mean, running the commands "ifconfig –a" doesn''t show any eth0 interface just lo. In the /sys/class/net directory

Hi All, I am new to Xen, and would like to know if anyone can help with a problem I have. I have a dual - Quad Core Intel 5535 VT 2.66 server, with 24G ram running CentOS5 dom0 and domU (both 64 bit). Everything works great and I am SUPER impressed with the efficiency of Xen (i have always been a UML man). I would however, like to run a single domU domain, with a single VCPU, but get the power

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

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

Greetings, I''m attempting to do gfx_passthru with the primary graphics adapter (03:00.0), passing it to a guest. I can unbind it from the host but when I fire up the guest OS my monitor loses signal from the graphics card and that''s that. The GFX card is dual DVI, I''ve tried both slots. Host is Linux 2.6.32.14-1.2.105.xendom0.fc12.x86_64, Guest is Windows 7. PC is an
