hello, I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs ''struct page'' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in

Implement a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests.

Hi list, I have a problem with a new laptop (reproducable on other machines too) and the xen hypervisor. When the hypervisor gets booted with VESA mode 800x600 I see some messages and then the screen contents is switched into a pattern of vertical colored lines and never comes back. In text mode all works well, but later the pattern appears when the X servers starts. I disabled VTd in the bios

Some firmware, such as OVMF relies on this value to get the size of extra memory above 4GB. Seabios in Xen doesn''t need this as it gets e820 directly from Xen. Rombios doesn''t read this value.

Hi all! I have recently purchased an Athlon X2 3800+ and I should like to install FreeBSD or OpenBSD in a HVM domU on Xen 3.0.3-1 dom0 (Debian packages). Is it possible? In such case, can someone recommend me a guide/howto to accomplish it? Thanks in advance.

Hi all, this patch series by Wei Liu implements a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests. The second version of this series includes the "or later" copyright clause for xen_apic.c and a fix to the return value of xen_apic_mem_read (thanks Peter for finding it out).

Hi, I have been trying to get Hyperthreading to work in a Windows HVM on Xen 4.1.2 as described in ''xmexample.hvm''. I think I have set it up correctly, but I can''t seem to get it to work. There is not much documentation on it and most topics are from years ago. I''m curious to know to whether this functionality is still supposed to work. I''m aware that

Hi all, I want to know if PMU in Xen HVM or PV is supported now? I have done a test that in the latest xen-unstable source, "perf" command cannot give right output in VMs. My CPU is Intel(R) Xeon(R) CPU E5620 @ 2.40GHz.

Hello folks, i do not get access to a physical disk with xen. I would like to install windows xp as hvm to the physical partition /dev/sdb1. I partioned the disk with cfdisk. Filesystem type is Linux (83). In my eyes the filesystem using hvm is insignificant(?). I tried the following configurations; probably a lot more than this. #disk = [ ''phy:hda1,hda1,r'' ] (comment from

RFC v2 of this series This series implements a basic test job for OVMF guest. The test case will install an OVMF guest and try to boot it. It is also possible to derive a debian HVM installation test case from ts-ovmf-debian-install - the only difference should be the BIOS option. I tested running the test script without specifying BIOS, it worked fine. I just didn''t figure out a

Hi, From cset 10921, ioemu: prefix is removed from disk config in /etc/xen/xmexample.hvm. Now HVM VBD driver is available, this thus raises a question: how would HVM domain know if one disk is a qemu-dm disk or a VBD disk? From current implementation, qemu-dm will recognize disk had, hdb, hdc, hdd, and VBD drive can recognize all disk (had~hdd, hde, hdf ...) . So the result is: qemu-dm will

Hi, when creating a bigger (> 50 GB) HVM guest with maxmem > memory we get softlockups from time to time. kernel: [ 802.084335] BUG: soft lockup - CPU#1 stuck for 22s! [xend:31351] I tracked this down to the call of xc_domain_set_pod_target() and further p2m_pod_set_mem_target(). Unfortunately I can this check only with xen-4.2.2 as I don''t have a machine with enough memory for

I am trying to run a new server with centos + xen using centos xen packages. After installation, we had to install a hardware raid card (areca) on the machine, and thus reload the os. It so happens the drivers shipped aren''t compatible with xen kernel, so i was forced to compile xen from source to compile areca drivers. Now with system running under compiled xen, i cannot boot my old

Hello, I don''t have a Vt-x machine on which I can test and see; I have a question regarding running qemu on Vt-x xen machines. xen-unstable has a config file example: dist/install/etc/xen/xmexample.hvm In this file we have the follwoing line: device_model = ''/usr/'' + arch_libdir + ''/xen/bin/qemu-dm'' The use manual says about the device_model:

I''m using Xen 3.1.0 on Debian etch, kernel 2.6.18-4-xen-amd64. One of the guests runs Windows XP. I am trying to install an application (Autodesk Inventor) that spans two DVDs. The config file for the domain in question contains: disk = [ ''phy:/dev/volgrp0/halebopp,ioemu:hda,w'', '',hdc:cdrom,r'' ] I ran "xm block-list halebopp --long" and

Hi. I can''t use the vnc option (VNC=1 in my xmexample.hvm file), when I use RedHat or Fedora on 64 bits. The qemu log, say /usr/lib64/xen/bin/qemu-dm: invalid option -- ''-vncconnect'' But when I use RedHat or Fedora 32 bits, works fine. There is a problem or incompatibility in the 64 bits Xen kernel and the VNC option ? Best regards Luis

1. Shouldn''t the GPLPV drivers take care of the (bad) clock drift I''m experiencing in my Windows XP HVM? Or is there some other way around this problem that I haven''t been able to find on Google? How can I tell if the GPLPV drivers are active? I''ve added the /gplpv switch to the boot.ini file and the virtual NIC is definitely using the GPLPV version but other

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 ;)
