similar to: virtual bios in hvmloader and qemu-dm

Hi, when user create the virtual machine, then: which code execute firstly, hvmloaer or qemu-dm?I have traced the codes flow and found qemu-dm run before hvmloader,right? And virtual bios code are both in hvmloader and qemu-dm, but I think it should be only one of virtual bios will be used to initialize the virutal device in qemu-dm.I find at the end of hvmloader it will jmp to 0xffff0, that

Hi all, I have some puzzle about hvmloader in the path /tools/firmware/, they are: 1: Is hvmloader running in non-root mode? 2: If hvmloader runs in non-root mode, does it have its pagetable? when set GUEST_CR3 in vmcs? 3: How can I find the value of GUEST_RIP in vmcs is set to the entry point of hvmloader,when virtual machine do it first vm entry. Much Thanks! - henanwxr

Hello, I found out what the problem in my other thread was, now I need to solve it: I need to port a modified Bochs bios to Xen x86. However, a file of the original source seems missing: acpi-dsdt.hex. It''s neither in the tools/firmware/hvmloader/acpi directory nor in the tools/firmware/rombios one. Also applying the diffs or manually editing the source probably won''t work since

Hi, when I boot my windows, the bios that is used is a qemu bios. I''m searching for the bios file on my system that is used by the hvmloader. I found bios files from bochs : -rw-r--r-- 1 root root 131072 2008-06-28 03:05 /usr/share/bochs/BIOS-bochs-latest -rw-r--r-- 1 root root 65536 2008-06-28 03:05 /usr/share/bochs/BIOS-bochs-legacy -rw-r--r-- 1 root root 131072 2008-06-28 03:05

Hi, any one help? I have puzzled by the question of device''s MMIO areas. I know a MMIO operation of guest os handled by VMM as follow steps: 1: Qemu-dm does its initialization and presents virtual devices for guest os. 2: virtual bios executes PCI_setup, it will scan the pci bus and get configure space of all devices,then virtual bios allocation system resources(like port I/O range,MMIO

How can I get the name of the virtual Registers present on an instruction. eg. %add18 = add nsw i32 %mul17, %37 in this case I want to extract the name of the virutal registers as "add18", "mul17","37". This can easily be done in the case of store Instruction eg. store i32 %add20, i32* %t, align 4 in this case functions like

Dear All, I have a problem with my VPS machine ...I used Centos OS and xen application : - I created domU called vps1 with this configuration : # more /etc/xen/vps1 kernel = "/usr/lib/xen/boot/hvmloader" builder = ''hvm'' memory = 1536 name = "vps1" vif = [ ''bridge=xenbr0,ip=202.162.218.236,mac=00:16:3E:12:18:36'' ] disk = [

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

Hi, I have 3.0.4-1 testing downloaded a week ago. I have enabled VT in the bios and rebuilt xen, but for some reason hvmloader does not get compiled and built. Under xen/tools/firmware I see hvmloader and when I try and do a make it complains of Install dev86 package to build firmware! (http://www.cix.co.uk/~mayday) Why is the hvmloader not built as part of Xen. I am using

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

Package: xen-utils-3.2-1 Version: 3.2.0-5 Severity: important virtinst Debian package is pointing the pygrub path to /usr/bin/ and hvmloader to /usr/lib/xen/boot/. I suggest ajust the path creating a symbolic link of /usr/lib/xen-3.2-1/bin/pygrub to /usr/bin/pygrub and /usr/lib/xen-3.2-1/boot/hvmloader to /usr/lib/xen/boot/hvmloader. In the last case, need ajust the directory

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 all: I am installing Windows XP SP2 on xen 3.0.4 with a VT able machine, but I can not find hvmloader in /usr/lib/xen/boot。I installed xen from source code, compile it, build it and installed it, does this matters? Then I installed xen 3.0.4 in Fedora6 by yum install xen* and copy the hvmloader to the former machine, It looks like winxp was started, but when I use vnc to connect to winxp, the

I installed XEN from source, since the binary did not install. The Xen source includes also tools/firmware/hvmloader To compile firmware it only shows a message: WARNING: Install dev86 package to build firmware! At the referred page http://www.cix.co.uk/~mayday I could not find anything about dev86. What do I need to do? I want to install as DomU2 Windows XP and need hvmloader. bye Ronald

Hello waldi, I'm working with agx in libvirt and virtinst packages, and I've detected a issue with pygrub and hvmloader path. The original source of virtinst package, point the pygrub path to /usr/lib and point the hvmloader path to /usr/lib/xen/boot. I suggest a symbolic link using alternatives police to correct it. Is it possible to change this in Xen package? Cheers, -- Marco

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 if this group is interested in tracking down the
