Hi list, I set the SuperAdmin Role on a AD group. I use my account in this group to use oVirt. I try today to add an Export Domain but I failed with this error in log : 2016-01-07 16:46:28,883 INFO [org.ovirt.engine.core.bll.storage.AttachStorageDomainToPoolCommand] (default task-1) [68d5410a] No permission found for user '8ac67747-110c-4125-86f1-1f52ca0e7705' or one of the groups he is member of, when running action 'AttachStorageDomainToPool', Required permissions are: Action type: 'ADMIN' Action group: 'MANIPULATE_STORAGE_DOMAIN' Object type: 'Storage' Object ID: 'c7dee64d-a27e-446e-8656-cef2d8ea42a6'. Where can I set the good permission ? Thanks a lot --- Kevin C

Still not possible to resize hosted engine disk?
by Cristian Mammoli 12 Jan '16

12 Jan '16

Hi, I'm using 3.6.2 pre and using hosted engine over iscsi. The appliance provisioned a 10GB virtual disk, even if the LUN is 100GB. How can I extend the vm disk? From the gui it doesn't seem to be possible (VM is not managed by the engine). Thanks

How to add faster NIC to oVirt cluser / host?
by Christophe TREFOIS 10 Jan '16

10 Jan '16

Dear all, I have currently a data center with two clusters and each cluster had 1 host. On one of the hosts, I now enabled 10 GbE NIC called p4p1. Currently everything is going over a 1 GbE NIC called em1 (ovirtmgmt). My question now is, how I could add my 10 GbE NIC to the setup for instance to use for transferring data during transmissions to export domain or to simply replace the 1 GbE? I prefer little downtime (eg only temp network loss), but a full downtime (shutting down) could be acceptable. Thank you for any pointers or starting points you could provide, Kind regards, — Christophe
