Hello, it seems that this is not error in libvirt. What libvirtd is trying to do is just read the file specified as a disk source. The NFS storage is most probably managed by VDSM and according to the log, for libvirt it is the same as any other file, so it looks to me like a NFS problem. Are you able to read from the file on host machine in the middle of the step 3 (after the disk is initialized)? When accessing the file on NFS share manually, I got "Permission denied" error, so the file is really not readable. After trying to reproduce it, using different NFS storage, the I/O error doesn't appeared in the log, so it seems, that the issue is related to the NFS share itself, maybe by incorrectly set permissions (I don't have access to the original NFS host, so I cannot check it). Anyway, after upgrading to libvirt-0.9.10-9.el6.x86_64 (and vdsm from 4.9.6-5 to 4.9.6-6), the problem with running VM has disappeared. Instead, new similar issue with shutting down VM appeared, but I am starting to be convinced, that it is related to vdsm and not to libvirt. So from my point of view, we can close this bug as it is no longer valid. As this is not a bug in libvirt and it seems to be resolved now, I'm closing this as NOTABUG as agreed with the reporter. |
