[Users] high availability via fencing
by Ian Levesque 26 Apr '12

26 Apr '12

Hello, I'm testing ovirt for potential deployment and one of the metrics for its success relies on the high availability feature. In my research on this feature, I found scattered documentation indicating that fencing is a prerequisite. On my test hardware, I don't have any LOM/IPMI but I see that APC managed PDUs are supported, which I do have. The problem is when I try to configure Power Management to use the "apc" type, I get this error: Test Failed, Host Status is: unknown. The fence-agent script reported the following error: Failed: You have to enter plug number Please use '-h' for usage ovirt-engine/engine.log tells me: 2012-04-20 11:32:44,595 INFO [org.ovirt.engine.core.bll.FencingExecutor] (http--0.0.0.0-8443-5) Executing <Status> Power Management command, Proxy Host:heilig, Agent:apc, Target Host:, Management IP:134.174.x.x, User:ovirt, Options:port=22,secure=true,slot=1 2012-04-20 11:32:44,598 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8443-5) START, FenceVdsVDSCommand(vdsId = 6de5e3fa-8a33-11e1-b3f9-003048c85226, targetVdsId = 60087c5e-8a3b-11e1-b15d-003048c85226, action = Status, ip = 134.174.x.x, port = , type = apc, user = ovirt, password = ******, options = 'port=22,secure=true,slot=1'), log id: 57f86a56 2012-04-20 11:32:44,696 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8443-5) FINISH, FenceVdsVDSCommand, return: Test Failed, Host Status is: unknown. The fence-agent script reported the following error: Failed: You have to enter plug number Please use '-h' for usage I've tried to add "port=1" to the Options field but that seems to have no effect. Any ideas? Is there any way to configure a "dumb" power management / fencing configuration for testing? Cheers, Ian

[Users] webadmin: Open Console button not working
by Adam Litke 26 Apr '12

26 Apr '12

Hi, I am running bleeding-edge ovirt-engine and I am finding that the Open Console button in the webadmin does not work. The VM is spice-enabled and the button in the gui is active. Clicking the button seems to have no effect. I do see this message being thrown in Firebug each time I click the button: Wed Apr 25 16:43:13 GMT-500 2012 com.google.gwt.logging.client.LogConfiguration SEVERE: Cannot find constant 'VdcActionType___SetVmTicket'; expecting a method name java.util.MissingResourceException: Cannot find constant 'VdcActionType___SetVmTicket'; expecting a method name at Unknown.e3d(Unknown Source) at Unknown.kDj(Unknown Source) at Unknown.gDj(Unknown Source) at Unknown.tWg(Unknown Source) at Unknown.a_h(Unknown Source) at Unknown.Y$h(Unknown Source) at Unknown.X_h(Unknown Source) at Unknown.__h(Unknown Source) at Unknown.MXc(Unknown Source) at Unknown.eA(Unknown Source) at Unknown.GA(Unknown Source) at Unknown.anonymous(Unknown Source) at Unknown.Gh(Unknown Source) at Unknown.Jh(Unknown Source) at Unknown.anonymous(Unknown Source) at Unknown.anonymous(Unknown Source) Is this a known issue? -- Adam Litke <agl(a)us.ibm.com> IBM Linux Technology Center

[Users] No Balloon Device
by David Metcalf 26 Apr '12

26 Apr '12

I have installed the memory balloon driver in my Windows guest but the driver says it can not start. I have also found no reference to the balloon device when looking at the qemu command line arguments of the process. Is there some way to add the balloon device I missed?

[Users] REST API query syntax
by Hui Kai Ran 26 Apr '12

26 Apr '12

Hi, all I learned some query language from "REST API User Guid" to get a reduced result list, for example: /api/storagedomains?search=name%3D*iso* it works. but the following querys do not work /api/storagedomains?search=type%3Diso /api/storagedomains?search=id%3D3f00108a-5c0e-4723-aa88-0013773bf122 /api/vms?search=display.type%3Dvnc I don't know what is the difference between them, and which property can be act as the part of query ? thanks!

[Users] ovirt and NAT/Internal Networks
by Dead Horse 25 Apr '12

25 Apr '12

I have tried to create a NAT network within ovirt for guests to use via libvirt/virsh as the vdsm@rhevh on an ovirt node. Something like this: virsh # net-info nat Name nat UUID b09d09a8-ebbd-476d-9045-e66012c9e83d Active: yes Persistent: yes Autostart: yes Bridge: natbr0 virsh # net-list --all Name State Autostart ----------------------------------------- nat active yes vdsm-natbr0 active yes vdsm-ovirtmgmt active yes virsh # virsh # net-edit nat <network> <name>nat</name> <uuid>b09d09a8-ebbd-476d-9045-e66012c9e83d</uuid> <forward mode='nat'/> <bridge name='natbr0' stp='on' delay='0' /> <mac address='52:54:00:9D:82:DE'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254' /> </dhcp> </ip> </network> Set net.ipv4.ip_forward = 1 in sysctl.conf This is basically the default libvirt NAT network. Connecting a VM directly to it via cli (qemu-kvm) works perfectly fine on the ovirt host itself but the ovirt manager UI does not seem to pick up on it or allow for creation of such a network for guests to use. Since the ovirt manager UI did not allow I dug into the database and added entries which seem to have been necessary by hand to the following engine database tables: table: network table: network_cluster table: vds_interface table: vds_interface_statistics The result was the network did show up under cluster logical networks. However the network still does not show up under the host Network Interfaces UI. Was able to create VM and attach the natbr0 network to it and NAT was indeed working. (EG: DNSmasq assigned address). The guest was able to communicate out and without extensive testing things seemed to work. This was very painful to do (and hacky). Thus it would be very nice if since this is OOB functionality of libvirt/KVM, if ovirt would allow for it to be used. The ability to provide NAT or internal networks to guests would quite useful. - DHC

[Users] can't get VM working (no ISO images, no Console)
by Frank Wall 24 Apr '12

24 Apr '12

Hi, I've setup a test instance of ovirt like this... - setup ovirt engine on Fedora 16 using yum (ovirt-engine-3.0.0_0001-1.6.fc16.x86_64) - setup ovirt node "ovirt-node1" using the ISO image ovirt-node-iso-2.3.0-1.0.fc16.iso - created a new datacenter with NFS storage ("datacenter2") - created a new cluster ("cluster2") - added ovirt node "ovirt-node1" to cluster "cluster2" - created an NFS storage for virtual machines ("nfs_storage1") - created an NFS storage for ISO images ("iso_images1") - created a new VM on "cluster2" with disk space provided by "nfs_storage1" ...but I fail to get any VM working. First of all, I've uploaded an ISO image with the iso-uploader. I can verify that it was uploaded successfully: [root@ovirt-engine ~]# engine-iso-uploader -v -i iso_images1 upload FreeBSD-8.2-RELEASE-amd64-disc1.iso Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): DEBUG: URL is https://ovirt-engine.EXAMPLE.COM:8443/api/storagedomains?search=name%3Diso_… DEBUG: Returned XML is <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <storage_domains> <storage_domain href="/api/storagedomains/b2d11688-84ce-40ef-b10f-f036ac806cf9" id="b2d11688-84ce-40ef-b10f-f036ac806cf9"> <name>iso_images1</name> <link href="/api/storagedomains/b2d11688-84ce-40ef-b10f-f036ac806cf9/permissions" rel="permissions"/> <link href="/api/storagedomains/b2d11688-84ce-40ef-b10f-f036ac806cf9/files" rel="files"/> <type>iso</type> <master>false</master> <storage> <type>nfs</type> <address>192.168.200.108</address> <path>/mnt/iso1</path> </storage> <available>15032385536</available> <used>3221225472</used> <committed>0</committed> <storage_format>v1</storage_format> </storage_domain> </storage_domains> DEBUG: id=b2d11688-84ce-40ef-b10f-f036ac806cf9 address=192.168.200.108 path=/mnt/iso1 DEBUG: local NFS mount point is /tmp/tmpxG6M3H DEBUG: NFS mount command (/bin/mount -t nfs -o rw,sync,soft 192.168.200.108:/mnt/iso1 /tmp/tmpxG6M3H) DEBUG: /bin/mount -t nfs -o rw,sync,soft 192.168.200.108:/mnt/iso1 /tmp/tmpxG6M3H DEBUG: _cmds(['/bin/mount', '-t', 'nfs', '-o', 'rw,sync,soft', '192.168.200.108:/mnt/iso1', '/tmp/tmpxG6M3H']) DEBUG: returncode(0) DEBUG: STDOUT() DEBUG: STDERR() ERROR: FreeBSD-8.2-RELEASE-amd64-disc1.iso exists on 192.168.200.108.

Besides that my test VM is in status "Up", but I can't select the "console" option, it is grayed out. So maybe you can advise me how to get the first test VM working. I'd like to continue with further tests as soon as possible :-) Thanks - Frank

[Users] UPDATE: oVirt 3.1 release date changed
by Ofer Schreiber 24 Apr '12

24 Apr '12

Due to multiple integration issues (Java 7, Fedora 17 and JBoss official rpm support) we've decided to postpone the next release of oVirt [1] to June 27th. This one month delay will hopefully give us enough time to stabilize all the different layers of oVirt, and produce a better release. Stay tuned, -- Ofer Schreiber oVirt Release Manager [1] http://www.ovirt.org/wiki/Second_Release
