I wasn't expecting this to work since it does not make sense to me= , making a parallel with the iSCSI problem. I'm starting to believe that's something just bad. Perhaps the Storage syst= em is running with something broken or the host machine is just unstable. I will consider this as solved, since further inside the oVirt Engine panel= I was able to mount and use the same iSCSI sharing. But let me ask for sincere answers here: 1. oVirt is feature complete comparing to RHEV? 2. Should I migrate from XenServer to oVirt? This is biased, I know, but I = would like to hear opinions. The folks with @redhat.com email addresses wil= l know how to advocate in favor of oVirt. 3. Some "journalists" says that oVirt is like Fedora in comparison to RHEL,= is this really true? Or it's more aligned with a CentOS-like release? Beca= use Fedora isn't really an Enterprise OS, and I was looking for an Enterpri= se Hypervisor. I'm aware that oVirt is the upstream from RHEV. 4. There is any good SPICE client for macOS? Or should I just use the HTML5= version instead? Thanks, V.
