No traffic on dummy interface
by Alan Murrell 31 Jan '16

31 Jan '16

Hello, I am running Ovirt 3.6.1 on CentOS 7.1 in a single server, hosted engine setup. I have created 10 dummy dummy interfaces names 'dummy_[0-9]'. Ovirt sees them, and in "Networks" for my cluster, I created 10 10 "internal" networks called 'Internal_[0-9]'. In the "Hosts" tab, in the "Network Interfaces" tab for my host, I assigned the 'dummy_*' interfaces tot he appropriate 'Internal_*' network (i.e., dummy_0 -> Internal_0, dummy_1 -> Internal_1, etc.) I have create two VMs and assigned a NIC interface on each attached to the 'Internal_0' network. I gave the interfaces on the gusts an IP int he same subnet, but they cannot talk to each other. When I try to ping one from the other, here is the response I get (public IPs redacted): --- START --- C:\Users\Administrator>ping 192.168.100.12 Pinging 192.168.100.12 with 32 bytes of data: Reply from 192.168.100.20: Destination host unreachable. Reply from XX.XXX.XX.XX: TTL expired in transit. Request timed out. Reply from XX.XXX.XX.XX: TTL expired in transit. Ping statistics for 192.168.100.12: Packets: Sent = 4, Received = 3, Lost = 1 (25% loss), --- END --- The IP of the PC I am pinging from is '192.168.100.20' I have been able to setup internal networks like this before, but seem to be missing something and I am not sure what? Here is what the dummy_0 interface shows when I run 'ip addr show': --- START --- 7: dummy_0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master Internal_0 state UNKNOWN link/ether 0e:a2:6b:54:1a:91 brd ff:ff:ff:ff:ff:ff --- END --- and Internal_0 looks like this: --- START --- 20: Internal_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 0e:a2:6b:54:1a:91 brd ff:ff:ff:ff:ff:ff inet6 fe80::dc07:84ff:fe1b:60cb/64 scope link valid_lft forever preferred_lft forever --- END --- I am not sure what other info you need, so please do let me know. I did see this: <http://blog.duderamos.com/internal-isolated-networks-on-ovirt/> and except that I use 'dummy_*' instead of 'dummy*', my setup is the same. Thanks, in advance, for your help on this. Regards, Alan

VDI question: How much disk space used?
by Alan Murrell 30 Jan '16

30 Jan '16

Hello, I have a question about VDI and the use of a VM pool. Are the VMs that are part of the pool linked clones or full clones of the pool's template VM? Let's say my template VM has a HDD of 64GB, fully allocated. I create a VM pool that uses that template and the pool consists of 5 VMs. Do I need to have 64GB x 5 = 320GB of disk space available (actually 384GB, counting the template VM), or just the 64GB of the template VM + whatever temporary space is used by each VM for the temporary changes made while a user is using the VM? (I hope that makes sense?) Thanks! :-) Regards, Alan

Any help you could give would be appreciated! Thanks, Adam

FOSDEM 2016 is just a few short weeks away, and I'm happy to share with you the full details about our community presence at the conference. ======= Virt & IaaS Devroom ======= Just a reminder that the full schedule is published on the FOSDEM website[1], and we have some great presentations from our community members for you to learn from. ======= oVirt/Foreman Stand ======= This year we will share a stand with our friends from the Foreman project. Stop by to say hello, grab swag, and enjoy some cool demos! **STAND VOLUNTEERS WANTED** If you're attending FOSDEM and would like to help us out, we'd love to have you there! This is a great opportunity to chat about oVirt with FOSDEM attendees and meet other community members from all over the world. Special surprise swag is reserved for booth volunteers! Please sign up for booth shifts in the etherpad[2] (lines 11-33). One of our core contributors will also be at the booth to support and co-pilot each shift. ======= Social Event on Saturday ======= In previous years, we had informal social gatherings for our community members on Saturday evening.

ovirt-3.6 and glusterfs doc

I'm trying to setup a ovirt3.6.2 cluster on centos7.2 and am having problems finding a doc that explains how to setup gluster storage for it. If I try to create a Storage domain with storage type GlusterFS it comes back with "General Exception". I'm not using Hosted-engine, engine is on a separate host by its self. I have 3 nodes, all running centos7.2. vdsm.log: jsonrpc.Executor/0::DEBUG::2016-01-29 11:06:35,023::__init__::503::jsonrpc.JsonRpcServer::(_serveRequest) Calling 'StoragePool.connectStorageServer' in br idge with {u'connectionParams': [{u'id': u'00000000-0000-0000-0000-000000000000', u'connection': u'ovirt3.test.j2noc.com:/gluster-store', u'iqn': u'', u'u ser': u'', u'tpgt': u'1', u'vfs_type': u'glusterfs', u'password': '********', u'port': u''}], u'storagepoolID': u'00000000-0000-0000-0000-000000000000', u 'domainType': 7} jsonrpc.Executor/0::DEBUG::2016-01-29 11:06:35,024::task::595::Storage.TaskManager.Task::(_updateState) Task=`e49fc739-faaf-40f1-b512-868b936fbcc1`::movin g from state init -> state preparing jsonrpc.Executor/0::INFO::2016-01-29 11:06:35,024::logUtils::48::dispatcher::(wrapper) Run and protect: connectStorageServer(domType=7, spUUID=u'00000000- 0000-0000-0000-000000000000', conList=[{u'id': u'00000000-0000-0000-0000-000000000000', u'connection': u'ovirt3.test.j2noc.com:/gluster-store', u'iqn': u' ', u'user': u'', u'tpgt': u'1', u'vfs_type': u'glusterfs', u'password': '********', u'port': u''}], options=None) jsonrpc.Executor/0::ERROR::2016-01-29 11:06:35,120::hsm::2465::Storage.HSM::(connectStorageServer) Could not connect to storageServer Traceback (most recent call last): File "/usr/share/vdsm/storage/hsm.py", line 2462, in connectStorageServer conObj.connect() File "/usr/share/vdsm/storage/storageServer.py", line 220, in connect self.validate() Cloud Services for Business www.j2.com j2 | eFax | eVoice | FuseMail | Campaigner | KeepItSafe | Onebox This email, its contents and attachments contain information from j2 Global, Inc. and/or its affiliates which may be privileged, confidential or otherwise protected from disclosure.
