VT-d and the GPU
Like others on this list I am trying to employ the VTD-NEO patches in Xen 3.2 unstable to assign the internal graphics device to Dom1/Vista. I have removed the Cirrus Logic emulated device from qemu and replaced the Cirrus Logic vgabios with the the actual vgabios from my GPU. However I am hitting an xen assert and was hoping someone might be able to point me in the right direction. Below

Hello, I read in the announce of Xen 3.2.0 released that it has "preliminary support for a wider range of bootloaders in fully virtualised (HVM) guests, using full emulation of x86 ''real mode''" . I''d like to know what is the level of the emulation of x86 ''real mode''? I ask that because I tried to install OpenSuse 10.3 (I used the iso file

4.3.0-3 fresh build - hvmloader Triple fault on VCPU0
When using the 4.3.0-3/4.3.0-3+b1 xen packages from the Debian archive, things work fine. However, when we compile the xen=4.3.0-3 source package ourselves, we run into an issue launching an HVM. As soon as the HVM bios is loaded, VCPU0 gets a triple fault and the HVM is destroyed (this is with "loglvl=all guest_loglvl=all hvm_debug=3" boot options). (XEN) HVM1: Multiprocessor

pci-passthrough nic but no link
I hope someone can enlighten me. I have a quad-port Intel 82580 nic (igb driver) on my system and I''d like to dedicate each nic to a HVM via VT-d PCI passthrough. The IOMMU on my system seems to work, I can assign the PCI devices to my HVMs. The HVMs see the pci device and load their respective igb drivers, and ethtool -i eth0 works on each HVM, shows the drivers are loaded and the

Bug: Limitation of <=2GB RAM in domU persists with 4.3.0
I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

vpmu=1 and running 'perf top' within a PVHVM guest eventually hangs dom0 and hypervisor has stuck vCPUS. Romley-EP (model=45, stepping=2)
This issue I am encountering seems to only happen on multi-socket machines. It also does not help that the only multi-socket box I have is an Romley-EP (so two socket SandyBridge CPUs). The other SandyBridge boxes I''ve (one socket) are not showing this. Granted they are also a different model (42). The problem is that when I run ''perf top'' within an SMP PVHVM guest,

4.3.0-3 fresh build - hvmloader Triple fault on VCPU0
I've tracked down the issue to the seabios package being updated to 1.7.4-1 from 1.7.3-3. When Xen is built with the older version, everything works fine. In fact, I bisected the issue down to the following SeaBIOS commit: http://review.coreboot.org/gitweb?p=seabios.git;a=commit;h=e144bb7af49ca8756b7222a75811f3b85b0bc1f5 I don't know if this group is interested in tracking down the

RE: A question on vmx loader in xen - how and when rombiosis loaded into memory
Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

A question on vmx loader in xen - how and when rombios is loaded into memory
A "main" function is defined in Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c. In this main function, rombios, vgabios and vmxassist are copied to specified address, with following commands memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz); ... memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot, sizeof(etherboot)); ....

Hi, Was anyone able to run Solaris 10 10/08 as guest under a HVM domU Debian Etch (xen 3.0.3-1) or current Debian Lenny (xen 3.2-1)? In my case Solaris installation stops after boot kernel ; I can''t see anyhing after grub screen. I know that it is possible using Xen 3.3 (see [1]) but I don''t know if it possible with a previous Xen version Thanks, Álvaro [1]

FreeBSD boot loader on VT-x based Xen system
Folks -- I''m trying to run FreeBSD 6.0 on a VT-x based Xen system. I''m experiencing a problem where the boot loader is crashing before the FreeBSD kernel (proper) is loaded. The sequence of operations is that the VMX domain is constructed, the BIOS is executed, GRUB loads, I type the instructions to load FreeBSD (a boot loader) and that code begins to execute and then
