OVIRT-3.5-TEST-DAY-3 - Providing Neutron Appliance
by ybronhei 17 Sep '14

17 Sep '14

Hey, following the great demo in http://youtu.be/naLFSFwHI94 we successfully managed to use neutron to setup isolates network for 2 vms by using the neutron appliance image we didn't open new bugs on it, but we plan to use and play with it later on and we'll update if something will be found we saw that the mirrors for f19 are broken but it doesn't worth a bug, just wiki update (in http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-releas…) -- Yaniv Bronhaim.

OVIRT-3.5-TEST-DAY-3: backup/restore and disaster recovery
by Simone Tiraboschi 17 Sep '14

17 Sep '14

Hi, today I had to test how to recover a broken system using backup/restore tool [1] or disaster recovery procedure [2]. Unfortunately I really had a lot of troubles just trying to setup my test environment so no good news on that side. I was using two host: one for the engine, the other as an hypervisor. Both with latest fedora 19 updates. For a fault of mine I add oVirt 3.5 RC2 repository on the engine host but I forgot to do the same on the second host and it generates a lot of problems. I installed the ovirt engine, release 3.5 RC2, on the first host and from the web admin UI I was trying to add the second host. I discovered that using jsonrpc mode it doesn't check/enforce or at least advice about cluster compatibility level failing silently. I opened a bug for that [3]. Than I start using xmlrpc mode that suggested me to downgrade the cluster compatibility mode to 3.3; I did that but it still failed adding my host apparently due to SELinux or Gluster errors; I opened a bug also for that [4]. So I understood that I forgot to add oVirt 3.5 repo on the second host; I opened a bug against host-deploy with install rpms but doesn't handle RPM repos. On my opinion it would make the setup more user friendly or at least more controllable for us [5]. So I added the yum repository and I tried again; I noticed that host-deploy upgrades vdsm stuff but it wasn't enough to get 3.5 compatibility level so, investigating it a bit, I noticed that host-deploy upgrades vdsm stuff but completely ignores libvirt one generating a nonworking setup; I opened a bug also for that [6]. At the end, after manually upgrade libvirt rpms I was able to add my host. Than I briefly tested backup/restore and disaster recovery procedures which seam to work as expected. So, at the end, on my opinion we have still to work a bit more to make the setup more user friendly.

OVIRT-3.5-TEST-DAY-3: replace XML-rpc with JSON-rpc
by Francesco Romani 17 Sep '14

17 Sep '14

Hi everyone of this test day I played with the new JSON-rpc transport, which is enabled by default. I set up from scratch two hypervisors running on RHEL 6.5, while Engine was running on F19. I created everything from scratch and tested all the flows I known good enough, including less-then-common stuff. The list includes creating storage domains, VMs, hotplug/unplug disks, snapshots, migration, hibernation and dehibernation. On top of that, I prepared an environment to run more tests, that included create 200 VMs, started/stopped 100 of them to test. I kept an eye on the logs other than Engine. Everything I tried went OK, and logs look good to me. I run in a few hiccups, which I mention for the sake of completeness: - VDSM refused to start or run VMs initially: libvirt config included relics from past environment on the same box, not JSON-rpc fault. Fixed with new config and (later) a reboot. - Trying recovery, Engine took longer than expected to sync up with VDSM. I have not hard data and feeling is not enough to file a BZ, so I didn't. - Still trying recovery, one and just one time Engine had stale data from VDSM (reported two VMs as present which actually aren't). Not sure it was related to JSON-rpc, can't reproduce, so not filed a BZ. Since I need to continue profiling anyway (better late than never I guess), I include a couple of test to see if JSON-rpc makes any difference to JSON-rpc. Results will be posted on devel(a)ovirt.org and/or on the oVirt wiki. -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

[OVIRT-3.5-TEST-DAY-3] dwh and reports on separate host
by Martin Sivak 17 Sep '14

17 Sep '14

Hi, I installed fresh engine on CentOS 6.5 (inside a VM) and dwh + reports to other CentOS 6.5 VM. Except being a bit confused by the certificate signing step during the setup all went well and I can see that the dwh service is running and I can access the reports site. I started in the afternoon, because I had to reinstall my hosts first, so I might try poking around tomorrow as well. Also I do not have extra hosts atm, but I hope to have my nested virtualization environment back tomorrow to actually put some data to the reports. -- Martin Sivák msivak(a)redhat.com Red Hat Czech RHEV-M SLA / Brno, CZ

Virtual Machines reporting as paused
by Thomas Scofield 17 Sep '14

17 Sep '14

A large number of my virtual machines are reporting in a paused state but they are actually up and running. Unfortunately I don't look at this cluster very often so I don't know exactly when it got into this state, I believe it may have happened a couple months back when I deployed a change to /etc/vdsm/vdsm.conf to throttle virtual machines migrations. I deployed this change via puppet and had puppet cycle the vdsm daemon. All of the vdsm daemons in the cluster were restarted in a short period of time. Since this happened some time back all the logs have rotated off. I have tried restarting vdsmd and libvirtd, but that doesn't appear to return the virtual machines to an up state. The output of "vdsClient -s 0 getAllVmStats" reports them as paused, "virsh -r list --all" reports them as running. From the GUI I can click run and the VM will show “Up” in the GUI and vdsClient. But if I restart vdsm, the VM's revert back to displaying a paused state. I did find that the *.recovery files in /var/run/vdsm contain a status of Paused even when the GUI and vdsClient are reporting it as up. I did try and change the status in this file while vdsm was down and then start vdsm, but it had no effect and the entry in the *.recovery file which reverted to paused. p335 sasS'status' p336 S'Paused' Any idea what might have caused the VM's to report as paused and how to recover from it? I am running ovirt-3.3.4-1 and vdsm-4.13.3-4

VM Network Interfaces - bad cluster network and VLAN assignment
by J. Mikulec 17 Sep '14

17 Sep '14

Hello, I have 4 Cluster networks and I am trying to add 2 NICs to VM now: nic0 -> br0 nic1 -> br1 At ovirt-engine it seems ok, but assignment in qemu is incorrect - going to this: nic0 -> br1 nic1 -> br0 So nics belongs to incorrect bridges and so incorrect VLANs. It does oVirt totally unusable for me (we strictly use 0 network for public IPs and 1 for intranet use) :( With one NIC I not see this problem. http://tinypic.com/view.php?pic=29pzxbr&s=8#.VBjLUxYoEiw http://tinypic.com/view.php?pic=2hdd07m&s=8#.VBjLgRYoEiw Thank for help.

Cannot create disk image on storage domain NOT master
by Gabi C 17 Sep '14

17 Sep '14

Hello! - 1 oVirt Engine (not hosted), 4 nodes, 3 in "Default" datacenter, 1 in a local-storage type datacenter; - Recently upgraded from 3.4.2 to 3.4.3; "Default"Datacenter has, along "mandatory"ISO and Export domain, two storage domains "storage_gluster2" aprox 550Gb and "storage_gluster3" aprox 130 GB. As you can guess :-), the three nodes serve also as gluster bricks, each with 2 bricks in the above mentioned storage domains, both in replicated mode. Master domain is "storage_gluster3". After create new VM, trying to add new disk on "storage_gluster2 ", which is NOT master domain raise (ovirt-engine.log) -- Message: VDSGenericException: VDSErrorException: Failed to HSMGetAllTasksStatusesVDS, error = [Errno 2] No such file or directory: '/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/b694642b-4603-4dc6-ba36-c0d82ca83fa2/images/5de04fd7-a8a5-483a-be53-cffb17db3d94', code = 100, -- Exception: VDSGenericException: VDSErrorException: Failed to HSMGetAllTasksStatusesVDS, error = [Errno 2] No such file or directory: '/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/b694642b-4603-4dc6-ba36-c0d82ca83fa2/images/5de04fd7-a8a5-483a-be53-cffb17db3d94', code = 100 On SPM: vdsClient -s 0 getConnectedStoragePoolsList 5849b030-626e-47cb-ad90-3ce782d831b3 vdsClient -s 0 getStoragePoolInfo 5849b030-626e-47cb-ad90-3ce782d831b3 name = Default isoprefix = /rhev/data-center/mnt/10.125.1.193: _mnt_storage__filer1_export__nfs2_iso/bb09aac2-05d5-45c5-b573-ebff9292ad6d/images/11111111-1111-1111-1111-111111111111 pool_status = connected lver = 23 spm_id = 1 master_uuid = aa401118-fc30-4399-8f01-f1751f89fff4 version = 3 domains = b694642b-4603-4dc6-ba36-c0d82ca83fa2:Active,bb09aac2-05d5-45c5-b573-ebff9292ad6d:Active,aa401118-fc30-4399-8f01-f1751f89fff4:Active,62f795ed-486c-443d-93e9-2c16595fe546:Active type = GLUSTERFS master_ver = 1136 b694642b-4603-4dc6-ba36-c0d82ca83fa2 = {'status': 'Active', 'diskfree': '324000022528', 'isoprefix': '', 'alerts': [], 'disktotal': '590231371776', 'version': 3} bb09aac2-05d5-45c5-b573-ebff9292ad6d = {'status': 'Active', 'diskfree': '1904214016', 'isoprefix': '/rhev/data-center/mnt/10.125.1.193:_mnt_storage__filer1_export__nfs2_iso/bb09aac2-05d5-45c5-b573-ebff9292ad6d/images/11111111-1111-1111-1111-111111111111', 'alerts': [], 'disktotal': '8049917952', 'version': 0} aa401118-fc30-4399-8f01-f1751f89fff4 = {'status': 'Active', 'diskfree': '111680159744', 'isoprefix': '', 'alerts': [], 'disktotal': '144146563072', 'version': 3} 62f795ed-486c-443d-93e9-2c16595fe546 = {'status': 'Active', 'diskfree': '131499819008', 'isoprefix': '', 'alerts': [], 'disktotal': '234763583488', 'version': 0} mount ..... 127.0.0.1:gluster_data3 on /rhev/data-center/mnt/glusterSD/127.0.0.1:gluster__data3 type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) 127.0.0.1:gluster_data2 on /rhev/data-center/mnt/glusterSD/127.0.0.1:gluster__data2 type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) ........ ls -la /rhev/data-center/mnt/ total 20 drwxr-xr-x. 5 vdsm kvm 4096 Sep 2 16:46 . drwxr-xr-x. 5 vdsm kvm 4096 Sep 2 16:46 .. drwxrwsrwx+ 3 96 96 4096 Feb 7 2014 10.125.1.193: _mnt_storage__filer1_export__nfs1_export drwxrwsrwx+ 3 96 96 4096 May 8 17:16 10.125.1.193: _mnt_storage__filer1_export__nfs2_iso drwxr-xr-x. 5 vdsm kvm 4096 Sep 2 16:45 glusterSD but no: '/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/b694642b-4603-4dc6-ba36-c0d82ca83fa2/images/5de04fd7-a8a5-483a-be53-cffb17db3d94', as per error from engine log posted above.
