Hello there.
I still have some problems with the last pvetest repositary:

- I am using a local mounted shared directory for ISO repositary: if I attach an iso file to a VM, it doesn't start because it can't access the file. No problem if I use a local storage.

- I can't live migrate VM's with SATA disk drives (on both ceph and local mounted shared directories); I have read that it is a QEMU 1.4 problem, but what will we do now with already created VM's ?

Thanks, Fabrizio

should work, looks like a configuration issue? details about your local shared dir? dig deeper.

On my hosts I have moosefs client, and this is a local-mounted moosefs filesystem. With this configuration all was ok before the last upgrade; I used those shared folders for images, iso and backups.

I see...
But not I can't migrate VM's anymore... what will you do now in proxmox ?
 
We do not use moosefs, so I cannot say anything about this. so far sata disks cannot be migrated, follow the bugreport.

Moosefs has a client with fuse so i can have a local filesystem like nfs. It .
worked fine until this last upgrade

I think that I have found the problem. When the startup of the VM fails, I see in /var/log/daemon.log this command line:

-drive 'file=/mnt/mfsclusterISO/template/iso/Windows7.iso,if=none,id=drive-ide0,media=cdrom,aio=native,cache=none'

So, I tried to startup a VM with the disk image in the same MooseFS storage, and if I use cache=none the VM doesn't start with the same error; using cache=unsafe, it works.

So I think that something is changed in the Cd-Rom cache option in this last release.

Thanks, Fabrizio

PS: i just tried to edit manually the VM definition, and in the CD-Rom line I addedd a "cache=unsafe" option. And the VM started fine !
So, if it is not a problem, add a cache option to the CD-Rom definition.
Thanks again
