similar to: qemu-dm high cpu usage

Hi, Im trying to install Netware and Windows 2008 server but im having problems with it reading the ISO. Im guessing this is because im running version 3.2.1 debian packages so i want to upgrade to unstable and use the 3.4 deb packages. My problem is that there isn''t a kernel package so when booting you cant boot into xenified kernel mode. If i try and use a kernel from the

Hi, I am compiling Xen from source on FC9. On booting the Xen dom0 kernel it gives the following error: Volume group "VolGroup00" not found and ultimately the error that switchroot: mount failed: No such file or directory So my question is that why it fails to detect logical volumes?

Hello all, I have a PowerEdge 2950 that I am using to host Windows XP VM's under CentOS. I am experiencing poor performance in the Xen VM's. Any time I try to do something, the CPU usage (as reported by the Windows task manager) hits 100% for a few and then drops back down. This is causing the VM's to run sluggish and be quite annoying to use. Example.. I click IE.. cpu hits

XEN of RHEL5.x DOM0 provides a qemu-dm command at /usr/lib64/xen/bin/qemu-dm, Can I run libguestfs with it? I have tried run libguestfs with kqemu, but it always cause system hang.

Hi, I believe the package is ready: http://ftparchive.gplhost.com/debian/pool/lenny/main/x/xen-qemu-dm-3.4/xen-qemu-dm-3.4_3.4.2-1.dsc I asked Ian Jackson to sponsor it (he works for Citrix and is a DD), but it's been 2 weeks, and he seems busy with work. I'd be glad if someone was sponsoring the upload of this package in Debian SID, soon enough so that people will be able to test it

I have just attempted to boot a windows 7 vm in safe mode with networking on Xen 3.4.2 and found that it reboots a few seconds after the logon screen appears, perhaps somebody else on the list could test this and confirm that they see the same issue? The last few lines of the qemu-dm log show the following: gpe_en_write: addr=0x1f6c, val=0x8. gpe_en_write: addr=0x1f6d, val=0x0. gpe_en_write:

Hi, We just migrated xen on gentoo on amd64 from 4.0 to 4.1 and encountered a few issues that were not documented. Here is how we solved them and what issues are remaining: 1. Our config files were referring to the LVM devices like /dev/vg/domU-root with disk = [ ''phy:vg/domU-root,sda1,w'' ]. This does not work anymore, we have to include ''/dev/'': disk = [

Using an 8-way ES7000 with 32GB of ram, I''m running xen at changset 11217 with dom0_mem=3092M as a kernel parameter on a x86_64 hyperviser. It appears that qemu is adding too much overhead to virtual machines to display graphics. If I boot a sles9sp3 domVT in runlevel 5 with vga=0x314 for a graphicalboot, and immediately use vncviewer simply to watch the virtual machine as it boots,

I have couple of HVM guests on xen 3.2. When guests boot, qemu-dm uses alot of cpu for approx 20 minutes post boot then load drops to average 0.50. I did some debugging and see this is going on, I suspect display output is using the CPU. Disabling VNC and SDL didn''t help with the CPU usage. any ideas how to reduce the cpu or stop it all together? My setup is as following: Xen

Package: xen-utils-3.1-1 Version: 3.1.0-2 Severity: normal Hi, When running an HVM domain with qemu-dm, I get the following in the logs: /usr/lib/xen-3.1-1/bin/qemu-dm.debug: line 10: /usr/lib/xen/bin/qemu-dm: No such file or directory /usr/lib/xen-3.1-1/bin/qemu-dm.debug: line 10: exec: /usr/lib/xen/bin/qemu-dm: cannot execute: No such file or directory And indeed there is no xen/

One of my W2K3R2 domains just stopped working, and the ''qemu-dm'' process is in the ''defunct'' state, which means it has seg faulted or something... Of course this happens after it has been running perfectly for a week and we think all of these problems are behind us! There wasn''t time to attach the debugger to the process unfortunately... is there any

Hi, John Can you try the attached patch ? This issue can be reproduced on SMP platform, while the domain 0 is UP. The reason is, after finishing a dma request, the dma thread will trigger the interrupt and then clear the call back function. When guest get the interrupt , it will try to check the call back function, if it is set, then it will trigger a dma request again. So if the checking for

Add support for a xenstore dm command to flush qemu''s buffer cache. qemu will just keep mapping pages and not release them, which causes problems for the memory pager (since the page is mapped, it won''t get paged out). When the pager has trouble finding a page to page out, it asks qemu to flush its buffer, which releases all the page mappings. This makes it possible to find

Hi, We found a crash in qemu-dm contained in the xen-utils-4.1 package. You are being contacted because your are listed as one of the maintainer of xen-utils-4.1. We are planning to submit the bug to the Debian bug tracking system in two weeks. We wanted to give you a heads-up, so that you some time to assess the seriousness of the bug before it is publicly disclosed. The bug report that will

I have been google for a few days now trying to get the Citrix PV Drivers to work on a server 2008 R2 HVM guest. I get the machine up and running then I install the cirtix PV drivers. I have tried both making and not making the registry change. Once I reboot the server I get stuck at the boot screen. The xen log says: XENUTIL: WARNING: CloseFrontend: timed out in
