Currently HVM cmpxchg emulation is done by doing a normal emulated write, which is not atomic. This patch changes it to use a cmpxchg

Hi there! My problem is the following: I am experimenting with virtualization with XEN. I am running WinXP in a HVM host with a Debian Gnu/Linux (Etch) dom0. I am also using audio emulation (sb16). This way, sounds from WinXP work fine. And here comes the problem: The HVM guest completely reserves the audio device; other software can not use it. (mplayer says this: alsa-init: using ALSA

I was trying to install Ubuntu 7.10 on an HVM domain, when when the install kept hanging at a particular point. xm dmesg shows the following : (XEN) realmode.c:132:d28 Failed to emulate insn.

This patch adds a number of fp instructions needed for OS/2 to boot as a HVM guest on Intel/VT hardware. It appears to work fine, and OS/2 is now finally working on Intel/VT as well as AMD/SVM. I''m a little concerned about the "correctness" of the FSTSW emulation and the use of inline assembly directly using the corresponding ops for emulation. Wrt FSTSW, it is really two ops

Hi Ian, Natasha and I are interested in helping with the io emulation work for fully virtualized HVM guests you mentioned in your March 12th email: http://lists.xensource.com/archives/html/xen-devel/2006-03/msg00394.html In the post, you mentioned the following tasks: - get minios running on x86_64 - port xenbus/netfront/blkfront to minios - compile qemu-dm into minios - redirect IO to qemu-dm

I''ve been trying to install OpenSUSE 10.3 as an HVM guest without much success. I''ve been using the mini network installation image `openSUSE-10.3-GM-i386-mini.iso''. First I had to binary-edit the iso to turn off gfxboot, which breaks with current xen-unstable. (In theory you can turn off gfxboot by holding down shift but it is almost impossible to get the timing

Kip, Does the problem with Xen 3.1 in HVM/Intel manifest as those BTX halted errors (e.g. http://lists.xensource.com/archives/html/xen-users/2006-10/msg00014.html) ? If so, do you happen to know whether this problem has been solved in Xen 3.2 or 3.2.1? This message of yours was written this March, so I'm assuming that 3.2.1 will contain this fix? Can anybody confirm this? I'm having

Package: xen-utils-3.2-1 Version: 3.2.1-2 Severity: important Intel processors have a bug with Vt that causes problems with Xen real-mode emulation. This renders FreeBSD (and possibly other OS'es) unbootable in Xen with HVM. Later versions of Xen 3.2 (and 3.3) emulate real-mode instructions so this problem doesn't exist. I would provide the relevant patches, but I do not have much

When trying to start a FreeBSD 9.0 HVM guest I see the following line in qemu-dm-freebsd.log: qemu-dm: /src/xen-stable-hg/src/xen-4.1-testing.hg-build/tools/ioemu-dir/hw/eepro100.c:1320: eepro100_write4: Assertion `!"feature is missing in this emulation: " "unknown longword write"'' failed.

Hi Keir, For HVM guests, all cpuid Fn''s going through domain_cpuid() iterate over the loop and then return 0 for all four registers. Guests OS''s and cpuid tools in HVM which query for cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think, Xen emulates oldish 386/486 CPUs. This leads to strange boot failures, "your CPU does not support long mode" or

Due to recent changes in timer handling (specifically building hpet emulation on top of Xen system time and ensuring it is monotonic), I wonder if it now makes sense to: 1) change hvm default for hpet to 1 (was 0) 2) change hvm timer_mode default from 0 to 2 I encouraged adding the hvm hpet parameter and defaulting it to 0 because the virtual hpet was not reliable and many guests/versions

Hi, i managed to boot a VxWorks 6.5 Kernel on QEMU without kqemu acceleration. The bootloader and the precompiled Kernel, both belong to the Pentium 3 BSP, which was delivered with the evaluation version of windriver workbench 2.6 for "intel". Now I tried to boot the same VxWorks bootloader and Kernel inside a XEN HVM. I see a message from the bootloader "V1.6+++..." and the

Has anyone gotten networking in an HVM domain to work with the emulated NE2000 rather than the emulated PCnet? I have Linux running in an HVM domain just fine with pcnet. If I change the config file to say ne2000=1, the tun0, vif0.1, and xenbr0 devices get created in dom0, the kernel in the HVM domain brings up eth0 OK (NE2000 support is built into the kernel), but I can''t get dom0 to

Hi, to use the host keyboard and touchpad of my laptop while running a HVM guest with passthroughed primary gfx-card I wrote a simple emulation. To activate it change gfx_passthru=1 -> gfx_passthru=1001 in the domU config file. This was done this way to have a small footprint. Also the embedding in helper2.c is a little bit awkward. Another problem using this way is that the VT in dom0 is not
