Re: [ovirt-users] More 4.1 Networking Questions

And bingo! I totally spaced on the fact that the MAC pool would be the same on the two clusters. I changed the pool range (Configure->MAC Address Pools for anyone interested) on the 4.1 cluster and things are looking good again. Thank you, this was driving me nuts!

Hosted engine setup shooting dirty pool
by Jamie Lawrence 11 Apr '17

11 Apr '17

Or at least, refusing to mount a dirty pool. I’m having trouble getting the hosted engine installed. I have 4.1 set up, configured and functional, currently wired up with two VM hosts and three Gluster hosts. It is configured with a (temporary) NFS data storage domain, with the end-goal being two data domains on Gluster; one for the hosted engine, one for other VMs. The issue is that `hosted-engine` sees any gluster volumes offered as dirty. (I have been creating them via the command line right before attempting the hosted-engine migration; there is nothing in them at that stage.) I *think* what is happening is that ovirt-engine notices a newly created volume and has its way with the volume (visible in the GUI; the volume appears in the list), and the hosted-engine installer becomes upset about that. What I don’t know is what to do about that. Relevant log lines below. The installer almost sounds like it is asking me to remove the UUID-directory and whatnot, but I’m pretty sure that’s just going to leave me with two problems instead of fixing the first one. I’ve considered attempting to wire this together in the DB, which also seems like a great way to break things. I’ve even thought of using a Gluster cluster that Ovirt knows nothing about, mainly as an experiment to see if it would even work, but decided it doesn’t especially matter, as architecturally that would not work for production in our environment and I just need to get this up. So, can anyone spare a clue as to what is going wrong, and what to do about that? -j - - - - ovirt-hosted-engine-setup.log - - - - 2017-04-11 16:14:39 DEBUG otopi.plugins.gr_he_setup.storage.storage

Resize iSCSI lun f storage domain
by Gianluca Cecchi 11 Apr '17

11 Apr '17

Hello, my iSCSI storage domain in 4.1.1 is composed by 1 lun of size 1TB and there are two hosts accessing it. I have to extend this LUN to 4Tb. What is supposed to be done after having completed the resize operation at storage array level? I read here the workflow: http://www.ovirt.org/develop/release-management/features/storage/lun-resize/ Does this imply that I have to do nothing at host side? Normally inside a physical server connecting to iSCSI volumes I run the command "iscsiadm .... --rescan" and this one below is all my workflow (on CentOS 5.9, quite similar in CentOS 6.x, except the multipath refresh). Is it oVirt itself that takes in charge the iscsiadm --rescan command? BTW: the "edit domain" screenshot should become a "manage domain" screenshot now Thanks, Gianluca I want to extend my filesystem from 250Gb to 600Gb - current layout of FS, PV, multipath device [g.cecchi@dbatest ~]$ df -h Filesystem Size Used Avail Use% Mounted on ... /dev/mapper/VG_ORASAVE-LV_ORASAVE 247G 66G 178G 28% /orasave [root@dbatest ~]# pvs /dev/mpath/mpsave PV VG Fmt Attr PSize PFree /dev/mpath/mpsave VG_ORASAVE lvm2 a-- 250.00G 0 [root@dbatest ~]# multipath -l mpsave mpsave (36090a0585094695aed0f95af0601f066) dm-4 EQLOGIC,100E-00 [size=250G][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=0][active] \_ 12:0:0:0 sdc 8:32 [active][undef] \_ 11:0:0:0 sdd 8:48 [active][undef] - current configured iSCSI ifaces (ieth0 using eth0 and ieth1 using eth1) [root@dbatest ~]# iscsiadm -m node -P 1 ...

ovirt node 4.1.1.1
by Julius Bekontaktis 11 Apr '17

11 Apr '17

Hey guys, Yesterday I've upgraded my Ovirt Node 4.1.0 to 4.1.1.1 version. Everything looks fine except Network configuration part is missing. If I enter manually in url (/network) like in the older version - I get Not Found error. I've roll backed to previous version - network configuration part is OK, reverted back to new one - no networking configuration. How should I configure networks? In terminal, the old way ? Thanks for any comments. Maybe I am missing something. Regards Julius

Hi all We are contemplating moving away from our current iSCSI SAN to Dell/EMC Unity 300. I've seen one thread where the 300F is problematic and no resolution is posted. Is anyone else using tis with RHEV/oVirt? Any war stories? Thanks CC

Desktop virtualization and thin clients
by Giulio Casella 11 Apr '17

11 Apr '17

Hi, I'm evaluating some thin client to connect to ovirt VMs, used as desktop workstations. I really don't care about native client support, I distribute via PXE a custom linux OS launching remote viewer. I'd like to have good multimedia performance, at a reasonable price. Googling a little, I focused on a couple of vendor: https://www.igel.com and https://www.10zig.com/. Anyone has already tested those vendor products? which model? which is the (approx.) price? Obviously any hint on other vendors are welcome. The scenario is composed of about 1500 VMs, running on ovirt (RHV to say the truth), distributed over 3 datacenters, currently accessed using old (5-7 years) PC, that I'm planning to renew. TIA, Giulio

Python-SDK4: How to list user permissions?
by nicolas＠devels.es 11 Apr '17

11 Apr '17

Hi, I'm trying to get a user's list of permissions, i.e., list all permissions a user have on VMs and VmPools. In SDK3 that was easy as I could run (being 'u' a User object): for perm in u.permissions.list(): vm = perm.get_vm() vmpool = perm.get_vmpool() if vm or vmpool: print "User has some permissions!" In SDK4 I cannot reproduce the same logic. u.permissions returns an empty list ([]). What I have so far is something like this: for u in users_serv.list(): if u.user_name == 'admin@internal': continue vms_service = sys_serv.vms_service() for vm in vms_service.list(): vms = vms_service.vm_service(id=vm.id) ps = vms.permissions_service() for perm in ps.list(): perm_service = ps.permission_service(id=perm.id) getperm = perm_service.get() if getperm.user.user_name == u.user_name: print "Permission for %s" % (u.user_name) if getperm.vm: print "VM: %s" % (getperm.vm.id) if getperm.vm_pool: print "VmPool: %s" % (getperm.vm_pool.id) However, this seems a bit overkill. We have nearly 850 VMs and for a single user this takes about 25 minutes to run. Additionally, it doesn't seem to return any permission, although I know this user has some permissions over 2 VMs (not sure where is it messed up). I also tried using the system_service.permissions_service() but it seems to return only the global permissions. Is there an easier way to do this? Thanks!
