similar to: Do vm snapshot feature exist in qemu-dm as in VMware?

Hi everyone, I'm not clear about the principle of the vm snapshot based on qemu-dm, so the following below maybe a joke. Sorry for that... register_savevm() included in ioemu-qemu-xen/hw/*.c covers various kinds of hardware in order to save the state of current running vm. In this way, the file saved by the cmd of 'xm save domain snapshot.save' is of large size and the

Thanks. I have already previewed the xenctrl.h. The following is what I understand: libxc is compiled to a file name after 'xc**' endding with '.so', xend communicates with domain0 through xc and domain0 communicates with hypervisor through privcmd. What's the privcmd? ------------------ 原始邮件 ------------------ 发件人: "Wei

Package: xen-utils-common Version: 4.1.2-1 Severity: normal Hi, I was doing some experiments today with XL TOOLSTACK, and found few problems when trying to do PV domU boot. I was trying to run kfreebsd9 or linux-3.2 kernel in qemu using PV i386, and with simple configuration without any disks, nics or virtual framebuffer, kernel boots (and then kernel itselfs correctly fails with information

Hi - I''m trying to use the instructions here http://xen.pablolibo.com/doku.php to create a new VM but it''s not clear where the .cfg file should go and what to do next. I was thinking xe needs to install the vm from the /mnt/so_xen mount but i''m not sure. Are the steps on the site reasonable? Is there a way to install a vm from USB instead?  I don''t have an

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/

I am trying to use virsh's snapshot-create command on a VMWare vm that has multiple disks in its device list, but the command is failing with the error: "Could not create snapshot: FileNotFound - file [pool] filename.vmx". However, this command works if my vm only has one disk in its device list. I am using libvirt 0.9.10, and the storage pool is nfs mounted between the machine that

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

I have just installed Xen by following http://wiki.xen.org/wiki/Xen_Beginners_Guide All in all pretty good, however it mentions using the xl toolset but when I first installed only the xm toolset would work. This was great for creating linux based domains but it gave me an error about hvm when I tried creating a Windows domain. I then apt-get install xen-tools-common and edited /etc/default/xen

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.

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, Me and another sysadmin has independently been researching a problem where DomU randomly locks (Can’t reach it via xl console, no ping / SSH connection, shown as stuck in running-state in xentop) on two of our separate machines (installed completely independently): Dom0: Debian 7.0 with Xen version: 4.1.4 and xen-utils 4.1.4-3+deb7u1 Debian 7.1 with Xen version: 4.1 DomU: 7.0 7.1(.3)

Hi all, I''m not sure what qemu-dm does or how to debug its high CPU usage. Any one mind giving me a clue? - Brian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, when user create the virtual machine, then: which code execute firstly, hvmloaer or qemu-dm? And virtual bios code are both in hvmloader and qemu-dm, which bios will be used to initialize the virutal device in qemu-dm?

Hi all, thanks to Mats I managed to compile a custom Linux kernel (2.6.16.29) and Xen 3.0.3. I then did "apt-get bcc" (to be able to build "hvmloader") cd /usr/src/xen...src/tools/ make install Then I could launch Windows XP but I wouldn''t see the SDL window... because qemu-dm has a compile time dependency on SDL devel. "apt-get libsdl1.2-dev" I

Hi, > xen-utils-4.1 is not in unstable, so this is not really helpful. I can still install it in my VM and this page shows a xen-utils-4.1 in sid: http://packages.debian.org/sid/xen-utils-4.1. I'm not sure what you mean when you say it's not in unstable. > Could you please explain why "exit 1" is a crash? "exit 1" is obviously not a crash. However, qemu-dm
