similar to: Guest Virtual Bios in XEN

Hi, I am using Libvirt with XEN hypervisor to manage the VM. I see there are 3 kinds of Virtual BIOS for XEN Guest VM, they are ROMBIOS,SEABIOS, OVMF ( is disabled by default as XEN Supporters said ). But I don't know how to pass the BIOS options to the Guest from XML file. Could you please suggest how to change the Virtual BIOS for the Guest from XML file in Libvirt or give some clues to

Hi, These set of patches are affected by replacing bios_relocate hook with bios_load hook in hvmloader. The patches for code files config.h and hvmloader.c also contains part of the contents of Enabling UEFI BIOS(OVMF) support in Xen-unstable HVM. Is there any problem with these patches? Thank you very much. # HG changeset patch # User gbtju85@gmail.com # Replace bios_relocate hook with

The SeaBIOS ROM image may validly exceed 128k in size, it''s only our interface code that so far assumed that it wouldn''t. Remove that restriction by setting the base address depending on image size. Add a check to HVM loader so that too big images won''t result in silent guest failure anymore. Uncomment the intended build-time size check for rombios, moving it into a

When booting HVMs with SeaBIOS, the BIOS itself takes care of extracting option ROMs from the PCI devices. These ROMs are usually provided with by the device model (qemu). Thus, hvmloader should not require any longer the rombios, stdvga, cirrusvga or etherboot ROMs to be present. Also, the 32bitbios_support.c file is specific to rombios and should not be built when building hvmloader with

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.

This patch set mainly allows the user to build a seabios or rombios only version of hvmloader. In addition, when building a seabios only hvmloader, Option ROMs like vgabios and etherboot are no longer required, and therefore can be disabled from the build. Dependency on the bcc compiler can also be avoided the same way. v2: Separate patches for separate issues Introduced config option to

Hi Attilio I have updated to the upstream Xen and try to boot into OVMF bios. Instead of fetching the OVMF code from the git mirror, I just copy the OVMF bios to ovmf directory. I use the bios="ovmf" in the HVM config file. But, there is an error when I create the domain. root@gavin-laptop:~# xl create hvm_ubuntu.hvm Parsing config file /root/hvm_ubuntu.hvm WARNING: specifying

This bug, at its core, is that currently there is no supported solution for VGA passthrough on Xen for stable version Jessie from Debian. After browsing Xen's repositories, I found out that Xen did not claim to support VGA passthrough with the upstream qemu-xen device model until Sep 25, 2015, the date the xl.cfg man page was updated to indicate support for VGA passthrough with upstream

I advice maintainers for fast and easy improve hvm domUs support on xen debian packages when the xen 4.4 will be packaged to specifying seabios and qemu binary of debian packages from configure, see these patches for details: http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=5c7cbadaccca8dbb47f2c42ab1b5a8afac9275e3

This issue should be addressed in Xen and I''m

Hello I have recently had to reinstall Centos 7.5 to on host computer. I have not be able to set-up qemu to support the q35 chip set. I have several virtual machines that require q35. This is not my first install, I have configured libvirt on many machines in the past, it just worked, it has not required any manual configuration.

I ran into this when I was reviewing what was outstanding to get NetWare to run fully virtualized. The BIOS emulator code has the segment and offset backward in the returned buffer for the int 13h, fn 48h BIOS call. BTW: This is fixed in current Bochs emulator upstream code.

I recently installed VMware on CentOS 4.4 (using the single server CD). I installed VMware fine, and then installed the VMware-mui tools that allow me to use a Windows box to console to the server. From my Windows box, I can create VMs on the fly just fine. Interestingly, I can create virtual Debian boxes ok, but I can't create virtual CentOS boxes. What might I be missing? As soon as I
