Hi guys, I'm wondering whether libvirt supports live migration for the VM with PCI passthrough devices. or it must be assumed before live migration that all passthrough devices be unplugged? If so, all unplugged devices should be manually hot-plugged to the VM after migration?? Thanks.

Hello, I am trying run a simple VM (qemu1.4.2) on RHEL 6.5 through libvirt (0.10). virsh create throws the error: *​error: Failed to create domain from vm1.xml* *error: internal error process exited while connecting to monitor:*​ The libvirt log for VM shows: *libvir: error : cannot execute binary /usr/bin/qemu-system-x86_64: Permission denied* ​I am running VM as root and all disk

I'm trying to implement a virtualization API. I was testing migration with libvirt I got some problems. When I use the following command : *virsh migrate --live --persistent --copy-storage-all vm-clone1 qemu+ssh://server_ip/system* the migration works fine but in the destination host the migrated vm is paused and I can't unpause it and I need to reboot the vm to be able use it in the

Hi, Excuse me, I have a question when I reading the libvirt source codes. I have known the process of how libvirt start/manage qemu, since I need to write a driver based on libvirt. But one thing also confused, please give me some tips. 1. In qemu_command.c, there is a function call "cmd = virCommandNewArgList(emulator, "-S", NULL);", which

​Hello, I have been trying to track different phases of a live migration process. I am using libvirt ​with qemu-kvm. I am issuing migration commands using virsh. Now, I want to measure the time spent in each phase of live migration, e.g., pre-copy and stop-copy. I stumbled upon the file qemu_driver.c. It has functions like qemudDomainMigratePrepare2 qemudDomainMigratePerform

You might not have to wait that long - if you could help test these patches, it would be appreciated:

Hi, I think the API Reference for libvirt disappeared from libvirt.org: browsing to http://libvirt.org/html/libvirt-libvirt.html delivers no content. The content is still available via google cache http://webcache.googleusercontent.com/search?q=cache:libvirt.org/html/libvirt-libvirt.html So, is this removed on purpose? Or is this some bluff from my browser (but I checked this from different

Hi all, I'm investigating the ways to improve the live migration performance in libvirt. I have a question about the vm live storage migration. the platform is libvirt + qemu + kvm If we want to migrate a running vm with its virtual disk images to another node. we can use 'virsh migrate ....' commands. What if this vm has a number of disk-only external snapshots? In the current

You should check that you haven't got any stale Xen libraries from a previous installation lying around. You can check if they are being picked up by using ldd as Jim demonstrated. After cleaning up rerunning ldconfig is usually a good idea.
