Use of virtual disks

I do come from using VMWare and have been also been using oVirt for several= years. We've also paid for RHEV, but migration is held up at the moment. I am tryi= ng to prepare for that. My problem is how it does not appear to be so simple to utilize the VM disk= s. In VMWare it is so simple. Snapshot or not, in vSphere I can take the vi= rtual disk file and use it for another VM when needed. It doesn't make sens= e to me in oVirt. I have another entry here about my issue that lead to th= is need, where I am not able to delete snapshot files for those disks I was= attempting to live migrate and there was an issue... Now, the empty snapsh= ot files are preventing some VMs from starting. It seems I should be able t= o take the VM disk files, without the snapshots, and use them with another = VM. But, that does not appear possible from what I can tell in oVirt. I desperately need to get one specific VM going. The other two, no worries.= I was able to restore from backup, one of the effected VMs. The third is n= ot important at all and can easily by re-created. Is anyone experienced with taking VM disks from one and using them (without= snapshots) with another VM? I could really use some sort of workaround. Thanks if anyone can come up with a good answer that would help. -Robert L. --_000_CY1PR09MB02986AF1BA90BAD8F52448A087CE0CY1PR09MB0298namp_ Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <html> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Diso-8859-= 1"> <style type=3D"text/css" style=3D"display:none;"><!-- P {margin-top:0;margi= n-bottom:0;} --></style> </head> <body dir=3D"ltr"> <div id=3D"divtagdefaultwrapper" style=3D"font-size:12pt;color:#000000;font= -family:Calibri,Helvetica,sans-serif;" dir=3D"ltr"> <div>My first experience with this situation using oVirt.</div> <div>I do come from using VMWare and have been also been using oVirt for se= veral years.</div> <div>We've also paid for RHEV, but migration is held up at the moment.

Hi Robert, If I understand correctly you are trying to share disks between two VMs, In Ovirt you can set a disk as sharable by editing the disk properties. A shareable disk can be attached to multiple VMs. If you wish to detach a disk from one VM and attach it to another VM it is simple too, select the VM that hold the relevant disk and detach the disk from it, you will find the detached disk under the 'disks' tab. To attach the floating disk to another VM, select the desired VM, go to the disks tab and press 'attach'. You will see all the floating disks that exist in the data-center. I hope it helped, please ask if you have more questions.
