I am not clear with the working of hypervisor xen. How does an instruction executed by kernel in Ring0 of DomU gets mapped or executed by hypervisor and then is excuted in Dom0. Is this thing some where on the wiki page? -- Tapas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, DomU is a Win2008 R2 64 When i install the GPLPV drivers the network latency goes from 15ms to random numbers up to 1200ms and eventually dies. If you run a ping from the DomU to another host the network stays alive but the high latency is still there. Further more if i try and uninstall the network driver i am unable to use the old one (realtek) as it cannot detect the device.

Hey, everyone, I''m having some issues with a Xen DomU right related to performance. We have an application that cross-compiles a Linux distribution from scratch for embedded systems. We''re attempting to run this application inside a Xen DomU (paravirtualized, modified guest kernel), and the performance is really bad. The culprit seems to be high I/O wait times related to the

Hey, everyone, I''m running Xen 3.2 (SLES10) and trying to get an OpenSolaris PV domU to run correctly. I''ve followed a couple of the instruction sets out on the Xen wiki and other folks blogs, but I''m running into an issue with the domU crashing. The OpenSolaris version is the latest development release - 5.11-0.128. The config looks like this:

Hi, folks, I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)

I build a DomU kernel on RHEL AS5.1. But when I boot this Guest DomU with the kernel, it gives me error message: Error: (2, ''Invalid kernel'', ''xc_dom_compat_check: guest type xen-3.0-x86_32 not supported by xen kernel, sorry\n'') Can someone give me any suggestion about this problem? Thank you! Joe _______________________________________________ Xen-users

In my experiments with setting up a NAS as a VM, I can only successfully import three drives; the root drive, the cd and one more. However, I have plenty that I want to use: disk=[''file:/vserver/vm_disks/Patch.disk.xm,hda,w'', ''phy:/dev/sda,ioemu:hdd,w'', ''phy:/dev/sdb,ioemu:hde,w'', ''phy:sdc,ioemu:hdf,w'',

It worked with original  Xen 4.0, no matter of  some additional patching to support ZFS 24 has been done and 4.0 src.rpm has been rebuilt to reinstall 4.0   In particular,  virt-install fails to

Well, I seem to have developed a strange issue with the GPL PV drivers in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two of them, though, have started exhibiting a strange behavior with intermittent network connectivity. Basically, the network starts up and connects initially. After some

Hi, I have searched the question which I am asking.But if some one has mentioned on their blog or link some where they have mentioned as how they installed CentOS as DomU on Debian Lenny (dom0)running xen-3.2.1 and I should have a look Then please share it here. -- Tapas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

I''m running xen on SLES10SP2. It''s been much more stable than SP1, but I still occasionally have issues. For example, one of my servers (8 CPU/32GB RAM) has five sles pv domUs and five fully virtualized windows 2k3 domUs. It had been up for almost 60 days. Yesterday afternoon one of the sles domU''s stopped responding. I went to check on it and I couldn''t using

Hello I am new in XEN and Linux. I am trying the VGA passthru. I can xen-pciback.hide EtherNet, Serial Com port. But when I xen-pciback.hide my VGA. I can no longer login to the Linux(Fedora 12). Then how can I xm create a XP DomU guest? Can anyone help? I am using Intel Q35 MB with Intel Core2 CPU. _______________________________________________ Xen-users mailing list

Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with

This may be a better question for the Xen-Devel list, but I''ll start here... Does anyone know if there is any easy way to replace the gPXE ROM with a newer version in Xen? Also, anyone know if there are any plans to have some sort of option in the domU config file to specify a boot rom? Looks like qemu-dm has an "-option-rom" option - is there any way in Xen to make use of

I''m using Xen with SLES10 and am using NPIV to attach FC SAN disks to my domUs. I''ve resize one of the disks on my SAN and I''m wondering if there''s a way to force Xen to rescan/resize the block device without shutting down the domU or unmounting the volume.

I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)? >>> On 2008/06/16 at 16:07, Rudi Ahlers <Rudi@SoftDux.com> wrote: Itamar - IspBrasil wrote: > why you''re using hvm ? its slow > > > > Rudi Ahlers wrote: >> Hi all >> >> I''m running CentOS 5.1 x64 + Xen 3.0 & I

When trying to use the GPL PV drivers with Windows 7 x64 (and testsigning turned on), I get a BSOD with a STOP 0x00000101 error. There''s also an error at the top that says "A clock interrupt was not received on a secondary processor within the allocated time interval." Is this STOP error related to the HPET or other timing adjustments for Xen? Any advice on things I should
