i'm having difficulty running KVM virtual machines off of a glusterFS volume mounted using the glusterFS client. i am running centOS 6, 64-bit. <br><br>i am using virt-install to create my images but encountering the following error:<br>
<br>qemu: could not open disk image /mnt/myreplicatestvolume/testvm.img: Invalid argument<br>(see below for a more lengthy version of the error)<br><br>i have found an example of someone else having this issue as well but no solution was offered (<a href="http://gluster.org/pipermail/gluster-users/2011-February/006731.html" target="_blank">http://gluster.org/pipermail/gluster-users/2011-February/006731.html</a>). i also found the following FAQ entry that states that NFS should be used to store VM images (<a href="http://www.gluster.org/faq/index.php?sid=36929&lang=en&action=artikel&cat=3&id=5&artlang=en" target="_blank">http://www.gluster.org/faq/index.php?sid=36929&lang=en&action=artikel&cat=3&id=5&artlang=en</a>)<br>
<br>i would prefer to use the glusterFS client for the automatic fail-over that it offers. is this possible? <br><br>i am creating the VM as follows:<br><br>sudo virt-install --name testvm --ram 4096 --os-type='linux' --os-variant=rhel5.4 --disk path=/mnt/myreplicatestvolume/testvm.img,size=50 --network bridge:br0 --accelerate --vnc --mac=54:52:00:A1:B2:C3 --location <a href="http://server/centos/5.4/os/x86_64/" target="_blank">http://server/centos/5.4/os/x86_64/</a> -x "ks=<a href="http://server/kscfg/testvm.cfg" target="_blank">http://server/kscfg/testvm.cfg</a>" --uuid=00000000-0000-0000-0000-000000000001 --vcpus=4<br>
