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 failur...

Hi all, this is the tenth version of the patch series to introduce upstream qemu and seabios in the xen-unstable build system. Changes to v9: - rename QEMU_UPSTREAM_TAG to QEMU_UPSTREAM_REVISION: we are going to use it with a branch name by default; - set QEMU_UPSTREAM_REVISION to "master" by default; - set SEABIOS_UPSTREAM_URL to git://xenbits.xen.org/seabios.git by default;...

Pass PYTHON=$(PYTHON) to gmake when building seabios. This fixes seabios build error ''python not found'' along with the patches from Kevin O''Connor.

I've uploaded seabios 1.7.4-2 to debian archive which now ships 2 versions of the bios binary -- small 128Kb one and bios-256k.bin (with size = 256Kb, obviously). For now, both are built with Xen support. So for now, it is enough to just rebuild xen with seabios >= 1.7.4-2~ to get this fixed without patching. Howe...

Package: xen-utils-4.3 Version: 4.3.0-3 Severity: important Tags: upstream patch When using Xen compiled with seabios-1.7.4-1 (now in unstable/testing), HVMs fail immediately upon starting with a VCPU triple fault: (XEN) HVM1: Loading SeaBIOS ... (XEN) hvm.c:1253:d1 Triple fault on VCPU0 - invoking HVM shutdown action 1. This is because SeaBIOS can now be greater than 128k, which breaks an assumption in the hvmlo...

Hi For the latest seabios version, it said: Support for vga emulation over a serial port in SeaBIOS (sercon). So I want to know how can I find the application of this feature in libvirt? And whether my understanding is correct? There are no related instruction on the website: https://libvirt.org/ My understanding: (1) The...

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...

Hi: Anyone knows how to configure seabios with libvirt? Or Can I configure seabios in XML file? I know that could configre seabios with "qemu-system-x86_64 -fw_cfg",but how to with libvirt? thanks! dw

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...

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...

...t; </source> </hostdev> I also activated Intel IOMMU in Linux (and rebooted). Then, I issued a virsh start <domain>. libvirt is able to fire the VM, but then the OS inside doesn't boot at all. I tried to go deeper into debugging and it seems that the VM cannot pass SeaBIOS anymore. It gets stuck in seabios, it seems. No "Booting" sentence displayed, only version of SeaBIOS, when I watch VNC ouput. I tried to use <bios useserial='yes'/> with a console to the VM. Nothing is displayed on the console.
