Hello! I want to run windows in xen. My linux distrution in ubuntu 6.06 amd 64. I downloaded and installed xen 3.0.2 from binaries. I found that hvmloader is not included in binary distribution :-( So I try to compile it from sources. I get following error: cpp -P -DDEBUG -DTEXTADDR=0x000D0000 vmxassist.ld > vmxassist.tmp ld -o vmxassist -m elf_i386 -nostdlib --fatal-warnings -N -T

Hi, all I am new to xen, and just try to use the HVM feature of xen3.1. two issues i met: 1. fedora 7 guest can not boot grub is displaying the boot menu, but hang there. and from "xm top", seems the guest exhauses all the cpu. 2. sdl doesn''t work, i always need to use vnc client to connect to the console here are some info about my system. * cat /proc/cpuinfo * cat xm.hvm (my

Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

Hi, Does anybody installed FreeBSD to VT Xen Domain with success? I tired FreeBSD 6.0 Stable installer cd but after the SDL console bing up and the loader was fund I got the following messages scrolling on the console: BTX halted init=0000000d err=00000000 elf=00010046 eip=000090db eax=00050033 ebx=00042820 ecx=00000000 edx=0000a000 esi=00209701 ebi=0001f98 ebp=000d0000 esp=00001800 cs=0008

Folks -- I''m trying to run FreeBSD 6.0 on a VT-x based Xen system. I''m experiencing a problem where the boot loader is crashing before the FreeBSD kernel (proper) is loaded. The sequence of operations is that the VMX domain is constructed, the BIOS is executed, GRUB loads, I type the instructions to load FreeBSD (a boot loader) and that code begins to execute and then

Hi, Keir: the gdtr information in oldctx is an address for guest, not for vmxassist. When access descriptor on guest gdt, we need to go through guest page table if guest enable paging.

All, We are facing some issues bringing up a DomVT on Xen x86_64(changeset 9267). We created a disk image with dd 8 G in size. We then booted an associated Dom-VT with a CD-ROM and did net-install of the sles-9 OS. This completes successfully. Then, when the system is brought around for a reboot (having changed the boot option from cdrom to disk), the system hangs after the line

Is it possiable to boot the hdb windows in xen? i saw there are some threads about P2V in this mail list. will the P2V tools help? thanks

Memory mapped and port I/O is currently broken under VMX when the partition is running in VM8086 mode. The reason is that the instruction decoding support uses 32-bit opcode/address decodes rather 16-bit decodes. This patch fixes that. In addition, the patch adds support for the "stos" instruction decoding because this is a frequently used way to clear MMIO areas such as the screen. As

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

Not yet, but I don''t see any reason for it to work any differently.
