If anyone is still interested in this old thread, I have a rh7.3 image running under hvm. It''s a hack, but here''s what I did: Install rh7.3 in a vmware machine with vmware server. Booted off a live cd, ( I used a gentoo installer CD, but any live cd should work) Created a lvm volume on my Xen dom0 >From the liveCD, I use dd to copy the disk image to the lvm image (dd

Hi All, When tried to pass through 2 mpt2sas HBA to hvm guest, hvmloader paused with below: MPT BIOS Fault 09h encountered at adapter PCI(00h,04h,00h) Press any key to continue... Checked related codes and mostly like it caused by rombios did not loaded MPT BIOS properly, and lead MPT BIOS failed to bootup. config-file of the guest as below: ---------------------------------- # cat vm.cfg

I am having reports of PCI passthrough problems with SR-IOV, in particular it looks like we are hitting the warning at msi:635 and msi:648 in xen; see the following log: (XEN) [VT-D]iommu.c:1785: VT-d page table not sharing with EPT table xenbus dev backend/vbd/1/5696 error 6 opening device (XEN) PCI add Virtual Function 04:1a.0 (XEN) HVM1: HVM Loader (XEN) HVM1: Detected Xen v4.1.0.rc2.pre (XEN)

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

Hello, I''m attempting to run Windows XP in a domU using the PCs actual graphics card. I believe I''ve set everything up correctly, including the pciback module etc. I''ve set pciback to grab the graphics card and all the USB hosts as well: (from dmesg) pciback 0000:00:02.0: seizing device pciback 0000:00:02.1: seizing device pciback 0000:00:1a.0: seizing device pciback

Hello. Im trying to get hvm running on my amd64 am2 socket 2gb ram. 1st it as a Debian amd64 etch. 2st xen 3.0.3-2 debian build (more configs below) 3st acpi=1 apic=1 Problem is I can install winXP but after reboot i get black screen. If i press F8 i get menu of XP but can''t select anything ->frozen again If i try acpi=0 apic=0 and install XP it freezes before it XP boots

Hello, I''m trying to create a HVM virtual machine (windows guest) with 3G of memory but this isn''t working. Xen create the domain but nothing happens (the OS don''t start and the cpu time remains 0). Things start to work with 2000MB or below. Is there some kind of upper limit for HVM virtual machines? I''m using a Dell PowerEdge 8250 machine with 16GB of memory.

Am considering a new laptop, and I wonder if anyone here can share their Xen experiences with the newest Core 2 Duo CPUs, ref http://www.intel.com/products/processor/core2duo/specifications.htm The list at http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors doesn''t include any Core 2 Duos. Does that mean that people have had problems, or is the wiki just not up to date? I gather

(The list appears to have eaten my previous attempt to send this. Apologies if you receive multiple copies.) The attached patches allow you to use paravirtualised network and block interfaces from fully virtualised domains, based on Intel''s patches from a few months ago. These are significantly faster than the equivalent ioemu devices, sometimes by more than an order of magnitude.

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

When thinking about multithreading the device model, it occurred to me that it''s a little odd that we''re doing a memcmp to determine which portions of the VRAM has changed. Couldn''t we just use dirty page tracking in the shadow paging code? That should significantly lower the overhead of this plus I believe the infrastructure is already mostly there in the shadow2

Hello, I am currently using a Dell Poweredge SC 1435 at the moment and am trying to virtualize windows on xen however it seems windows does not really understand what its supposed to do. Anyone have an idea what could be the problem I think there is something windows doesn''t understand from the virtualized hardware. With WinXP I get a black screen on reboot (with a grey bar at

Hi, I created a 100 MB file image using dd: dd if=/dev/zero of=/xen/tmp_disk bs=1024k count=100 Then i created a file system in it: mkfs -t ext3 /xen/tmp_disk I mounted the disk and copied a file on it, which I would like to access: mount -o loop /xen/tmp_disk /mnt/tmp cp test_file.cfg /mnt/tmp umount /mnt/tmp Then I tried to distribute the disk to the hvm machine. With

Not yet, but I don''t see any reason for it to work any differently. I simply used vmware because it was convenient. -Adam | -----Original Message----- | From: Simon Gao [mailto:gao@schrodinger.com] | Sent: Thursday, October 05, 2006 11:22 AM | To: Adam Crews -X (acrews - Xerox at Cisco) | Cc: xen-users@lists.xensource.com; Mike Freemon | Subject: Re: [Xen-users]

This issue I am encountering seems to only happen on multi-socket machines. It also does not help that the only multi-socket box I have is an Romley-EP (so two socket SandyBridge CPUs). The other SandyBridge boxes I''ve (one socket) are not showing this. Granted they are also a different model (42). The problem is that when I run ''perf top'' within an SMP PVHVM guest,

I am trying to get QNX working with Xen. I''ve going about it in a similar way as installing windows with Xen, but when I start the guest up to install the OS it hangs on the line: ''Hit Esc for .altboot.......'' If anyone has managed to get this working, or has any ideas/advice for me here it would be greatly appreciated! Bryan

Hi Michael, I'm writing to follow up the previous discussion about memory barriers in virtio-net device implementations, and Cc'ing the DPDK list because I believe this is relevant to them too. First, thanks again for getting in touch and reviewing our code. I have now found a missed case where we *do* require a hardware memory barrier on x86 in our vhost/virtio-net device. That is when
