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)); .... But after searching the whole directory "firmware",...

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 seabios.

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...

Attached simple patch modifies the rombios and hvmloader Makefiles to default to an 8-way bochs bios for the hvmloader. Is there a reason to not define the mp config table by default for >1 processors (8), in the repository?

Add a check to HVM loader so that too big images won''t result in silent guest failure anymore.

I discovered the following facts: 1. Adding qemu-xen-traditional in a way supported by Xen also requires rombios which, like qemu-xen-traditional, is disabled in Debian's official build of Xen for Jessie. 2. After configuring the build for qemu-xen-traditional and rombios, the only binary package that is modified significantly is xen-utils-4.4, which is where the qemu-dm binary is insta...
