Hi, I'm experimenting with the migration function of virsh. I'm doing the migrate with following commands: virsh migrate --life --persistent --copy-storage-all --verbose --abort-on-error domain qemu+ssh://root@destination/system virsh migrate-setmaxdowntime domain 20000 However sometimes at the end of the migration, the guest isn't started on the destination host. So I'm left

Hello, I am very new to R (as my Subject probably indicates). I want to do something that should, I think, be very simple. I have five vectors in a list and I want to construct a covariance matrix out of them. Given a 5X5 matrix cvm1, and the list of vectors, cvm1_list, I thought the following would work (sorry cannot find code tags): for(i in 1:5){ for(j in 1:5){ cvm1[i,j] <-

Hi All, I am trying to compile libvirt tools from source on RHEL 4. I could get the sources compiled, but when I try to connect to libvirtd using QEMU+SSH I get the following error: error: failed to connect to the hypervisor error: authentication failed: unsupported authentication type 2 With root as the user, I could login, rest other users get the error. All authentication related settings

Hi All I was reading through this: http://kashyapc.com/2011/12/02/little-more-disk-io-perf-improvement-with-fallocateing-a-qcow2-disk/ I was basically searching for pointers on improving disk I/O. I wanted to know the purpose of preallocation=full & preallocation=metadata , What is the difference between them ? and which one would yield a better disk I/O speed ? Appreciate your

Thanks Kashyap for replying. QEMU has permissions to the directory which is having images. I will look into the AppArmor issue and find out more about this. Also as per suggestion from the link i have uncommented the user and group from the qemu.conf file - https://github.com/jedi4ever/veewee/issues/996 By checking more on the AppArmor and sVirt issue , i have modified the qemu.conf for
