So if I have 3 VMs that require 1500 and I have 3 hosts and they just happen to be scheduled one per host, my other 100 VMs that do support 9000 would be degraded. Instead, separate these 3 VMs to a different vnet and everything just works. When you change the vnet you're degrading all the VMs running on this host using this network. > > -Nathan > _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
