[libvirt] virsh migrate with libvirt-0.6.2: failed to start listening VM
by David Wilcox 21 Sep '09

21 Sep '09

Hello, I'm trying to migrate a vm from a fedora 11 host to another fedora 11 host. Both hosts are on the same subnet. Both machines have identical architectures. We use an nfs shared storage mounted, but both machines also have their own hard drives. I get the machines up and running alright. Here's the printout of virsh when I try to do the migration. # virsh list Id Name State ---------------------------------- 1 windowsxp running 2 potato running # virsh migrate 1 qemu+ssh://prodigy/system Password: error: operation failed: failed to start listening VM On the other machine, the log file that gets created under /var/log/libvirt/qemo/windowsxp.log LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -S -M pc -m 512 -smp 1 -name windowsxp -uuid 24d2fd62-ed4f-a321-e264-200b347cfa6c -monitor pty -pidfile /var/run/libvirt/qemu//windowsxp.pid -localtime -no-acpi -boot c -drive file=/var/lib/libvirt/images/windowsxp.img,if=ide,index=0,boot=on -drive file=/aml/iso/windows_xp_sp3.iso,if=ide,media=cdrom,index=2 -net nic,macaddr=54:52:00:01:f1:06,vlan=0 -net tap,fd=19,vlan=0 -serial pty -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:0 -soundhw es1370 -incoming tcp:0.0.0.0:49159 qemu: could not open disk image /var/lib/libvirt/images/windowsxp.img I would think that the virtual machine should copy from the one machine to the other. Isn't libvirt supposed to copy the image file? What's even stranger, I've been trying this for awhile. It's failed every time, except once when it succeded. I don't know what made it succeed in that case and fail in all the other cases. Thanks.

[libvirt] regarding the network information for Domain
by anuj rampal 18 Sep '09

18 Sep '09

Hi all, im trying to call libvirt api from windows. I have created a guest OS(windows) using the libvirt api from my windows machine. It gets created fine it also gets the the IP address from the DHCP also. So all works fine. Now to RDP into the machine what I have to do is 1. logon to my host machine. 2. open the guest OS using either "virt-viewer" or "virt-manager". 3. check out the IP address of the machine. 4. then RDP into the guest OS. My Question: Is there a way to find The IP address of the Guest OS.??? ---------------------------------------------------------------------------------------------------------------------------- im also trying to cross compile "virt-viewer 0.0.3" but this is what i get when i do make: [root@FC-11 virt-viewer-0.0.3]# make make all-recursive make[1]: Entering directory `/root/virt-viewer-0.0.3'

[libvirt] guests and pulseaudio fighting over audio devices
by Dave Allan 17 Sep '09

17 Sep '09

I noticed that when a KVM guest created with virt-manager is running on F10, sound on the physical host stops working. When all VMs are shutdown, sound starts working again. Removing the <sound> tag from the VM XML allows sound to work while the VM is booted. To further complicate troubleshooting, if audio is already playing when the guest is started it keeps playing, since pulse already has the device open. The message in /var/log/messages when I try to play audio is: pulseaudio[6492]: module-alsa-sink.c: Error opening PCM device front:0: Device or resource busy strace of pulseaudio shows: open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK) = -1 EBUSY (Device or resource busy) but fuser and lsof show nothing. A trivial test program also sees Device or resource busy when trying to open /dev/snd/pcmC0D0p I am in favor of removing the <sound> tag from the default configuration, since I don't use sound from within guests and I do use sound on my desktop, but perhaps this behavior is specific to my configuration. I haven't investigated it exhaustively. What does everybody else think? Dave

[libvirt] Resubmission: [PATCH 0/6] sVirt AppArmor security driver

Resubmitting based on feedback from this list. Notably, *alloc calls have been removed and syntax-check completes without error for all files.
