about HA or live migration
Hi, I was wondering to know if the same concept that have vmware about migrate machine between nodes is available in ovirt. The scenario start when i partner tell me that he have this features in vmware, he can move a vm between host without any impact, but the limitation is only three nodes per host, because it do like a special copy of memory and othres stuff every momento so if the host fail the machine instantaneously will be ready in the other host without any impact. is that possible in ovirt ? or what happen if a host crash with all vm that it have or if it have something similar like mark a vm very important and do a special task with it in case that everything crash.. or whatever other solution have.. I want to show that we have it on ovirt or can solve this kind of problem Regards -- --- Rondan Rino Certificado en LPIC-2 <https://cs.lpi.org/caf/Xamman/certification> LPI ID:LPI000209832 Verification Code:gbblvwyfxu Red Hat Certified Engineer -- RHCE -- RHCVA <https://www.redhat.com/wapps/training/certification/verify.html?certNumber=120-175-658&verify=Verify> Blog:http://www.itrestauracion.com.ar Cv: http://cv.rinorondan.com.ar <http://www.rinorondan.com.ar/> http://counter.li.org Linux User -> #517918 Viva La Santa Federacion!!

You had better starting to read oVirt Administrator Guide at http://www.ovirt.org/OVirt_Administration_Guide For you particular questions the answer is almost yes for all and you can read about them at 6.7.1 8.13 and 8.14 VMware FT (fault tolerance), as you describe in your scenario, is not available (yet) as far as I know...
