[Users] Gluster RDMA support
by Murphy-Olson, Daniel E. 15 Nov '13

15 Nov '13

Hi all, I'm trying to configure a gluster storage pool over RDMA protocol. I created the volume by hand, because RDMA is disabled in the volume creation interface due to a patch ~18 months ago. After the manual creation of the volume, it displays bot protocols as being configured.. However, in the XML configuration that is generated for libvirt, ?protocol=rdma is not appended to the path. Is there some template I can edit to add that, or is it buried in the code somewhere? I cannot seem to find where the vsdm clients are getting the url for the gluster volume. Thanks! ---- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science Division Argonne National Laboratory 630-252-0055

[Users] Failed to start JBoss AS
by Bob Doolittle 15 Nov '13

15 Nov '13

Hi, I had a working engine, using 3.3.0 on Fedora 19. I rebooted my engine, and JBoss AS won't come back up. I get the attached errors from server.log. Has anyone seen this before? Any suggestions on how to recover? How I got here: I had a working Engine (mach1 F19) and Host (mach2 F19), but needed to play some musical chairs with my hardware to utilize a 3rd machine (mach3 RH6). My goal is to have mach2 become Engine, and mach3 Host. I did the following: 1. Created an NFS share on mach3, and used it as NFS Export Storage from mach2. 2. Exported my VMs and templates to the Export storage. 3. Removed mach2 from my Datacenter 4. Shut down mach1 5. Installed fresh F19 on mach2 (my old host), and installed Engine 3.3.0 on it 6. Added mach3 as Host 7. Imported my VMs and Templates from the Export Storage At this point all looked well. I rebooted mach2, but it won't come back up. I'd appreciate any insight. Thanks, Bob

[Users] 32bit CentOS 6.4 on VirtualBox to oVirt on Fedora 19 64bit via virt-v2v
by Owen Williams 14 Nov '13

14 Nov '13

Hello, I've trying to move a 32bit CentOS 6.4 on VirtualBox to oVirt on Fedora 19 64bit via virt-v2v. The command I'm currently using is: virt-v2v -i libvirtxml -of qcow2 -oa sparse -o rhev -osd xxx.xxx.xxx.xxx:/usr/local/ovirt/exports --network ovirtmgmt /usr1/home/williams/Downloads/OpenAthens/VMs/OpenAthensLARuntime2.2.xml The exciting bit of the XML is: <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='disk' snapshot='no'> <source file='/usr1/home/williams/Downloads/OpenAthens/VMs/OpenAthens_LA_Runtime_2.2.img'/> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> </disk> </devices> The image is a RAW (taken from the working VirtualBox install) but I have tried the original image with the same result: virtio configured, but no virtio kernel found at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm I have looked at the code: /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm:~490 creating this and dumped the contents of the grub look up: Sys::VirtConvert::GuestfsHandle=HASH(0x433da98)< >/dev/VolGroup/lv_root< $VAR1 = bless( { 'onclose' => [ sub { "DUMMY" } ], 'g' => bless( { '_g' => 70645888, '_flags' => 0 }, 'Sys::Guestfs' ) }, 'Sys::VirtConvert::GuestfsHandle' ); If I tell the code to skip this section the result becomes: virt-v2v: Failed to find a kernel_pkg.i686 package to install Any ideas on how to solve this or what the solution might, please? Best regards, Owen.

[Users] Snapshot delele/merge broken. Was: Live storage migration snapshot removal (fails)
by Sander Grendelman 14 Nov '13

14 Nov '13

Snapshot deletion on preallocated FC domain disks is broken in ovirt-stable/3.3 Both online and offline snapshot deletion leads to an error and the snapshot state is changed to "BROKEN". When I apply the patch at http://gerrit.ovirt.org/#/c/19983/ from https://bugzilla.redhat.com/show_bug.cgi?id=1015071 snapshot deletion works again. Can/will this patch be backported to ovirt-stable?

[Users] Custom settings for Kernel Same-page Merging (KSM)?
by Frank Wall 14 Nov '13

14 Nov '13

Hi, recently I've noticed that ksmd is using quite a lot CPU on my oVirt node. While I have plenty RAM, my CPU is way slow. Thus ksmd is eating up the most limited ressource here. Is it supported to use custom settings for ksmd? I've noticed that it is handled by MoM: /etc/vdsm/mom.d/03-ksm.policy. May I just change some settings here, or is there a tuning parameter in oVirt engine? Couldn't find a matching one with engine-config. I'd like to use a higher value for sleep_millisecs to reduce CPU usage (with the possible side effect of higher RAM usage). Thanks - Frank

[Users] Installing Windows VMs
by Bob Doolittle 14 Nov '13

In the QuickStart Guide, it implies that you should find a virtual floppy image for virtio-win in the ISO_DOMAIN. Or at least I can find no information on where to find/populate that image before the Guide shows its use. However, in my default 3.3 installation, there was nothing pre-populated in my ISO_DOMAIN. Should there have been? Regards, Bob

Re: [Users] Default route on hosts
by Assaf Muller 14 Nov '13

14 Nov '13

Can users outside of the hosts' networks reach the VMs in the hosts? If you use netstat -rn it is expected that the gateway will be 0.0.0.0, as ifcfg-ovirtmgmt has DEFROUTE=yes and ifcfg-public has DEFROUTE=no, then ovirtmgmt's 'gateway' (0.0.0.0) will be determined as the host's default gateway. However with the new multiple gateways feature we configure source routing to make sure that traffic that comes (from the outside) in the public network's device will return the way it came in. You can use 'ip rule' to see the rules VDSM configures. It creates two rules and a routing table per device. You can use 'ip route show table %s' on each table, where the IDs can be obtained by 'ip rule'. ----- Original Message ----- From: "Chris Geddings" <chris.geddings(a)duke.edu> To: "Assaf Muller" <amuller(a)redhat.com> Sent: Tuesday, November 12, 2013 2:26:40 PM Subject: Re: [Users] Default route on hosts On Nov 12, 2013, at 3:32 AM, Assaf Muller <amuller(a)redhat.com> wrote: > oVirt 3.3 introduced a feature called multiple gateways which may assist you.

Now, my management network has a gateway of 0.0.0.0, as it is a completely simple network, so that may be part of the problem. I'm not sure the impact of a 0.0.0.0 as a gateway. I'm not sure how to poke at this further to figure out where the breakage is. Routing looks like it has gotten a little more complex, and I'm still operating with 'netstat -rn' and 'route add foo' type commands. --Chris
