[Users] Time keeping in Windows VM
by Martin Goldstone 21 Nov '13

21 Nov '13

Hi all, We're currently experiencing an issue in our production oVirt 3.2.2 environment (on CentOS 6.4) with time keeping on our Windows guests. It seems to have appeared around the time of the recent DST change. It's taken us a while to get to the bottom of this as some machines were created in the wrong timezone, which muddied the waters a bit. It appears that when Windows automatically updated time in the VMs, this new offset from UTC was not stored correctly, and the next time the host was shutdown and started back up, the clock was set incorrectly. We eventually managed to get this to be consistently reproducible: Set the clock an hour ahead; power off VM; power it back on; set the clock an hour back (ie return it to the original time), power off and power back on; observe that the clock has now shifted to an hour before the original time. This can be observed in the vm_dynamic table on the database. To be honest, I don't think that this an oVirt problem, as I've done some limited testing on another host using virt-manager/libvirt. If I edit the xml to set the clock offset to variable, using UTC as the basis and setting the adjustment to 3600 (mimicking how it would have been before the DST change), when I change the time in the VM back by an hour (as Windows would do automatically at DST change), the xml shows a new offset of -3600, so it seems when the clock is changed the offset it's putting in the XML is the offset based on the time from when the VM was started, not the offset from UTC. Does anyone have any suggestions? At the moment, the only things I can think of doing are either a) shutting down each VM and setting their offset to 0 in the vm_dynamic table before starting the back up again or b) setting the time forward and back an appropriate amount of time so that the offset becomes 0, shutting the VM down and powering it back on again.

[Users] Resizing the iscsi data domain
by Juan Pablo Lorier 21 Nov '13

21 Nov '13

Hi, I've resized the lun I'm using for data domain. I've changed the lun, rescaned the target with iscsiadm and reloaded multipath to get the new size. The thins is that though all the hosts sees the new size, ovirt doesn't. Do I need to run something to update the engine db? I'm running ovirt 3.2 Regards,

[Users] 3.4 planning sheet
by Itamar Heim 21 Nov '13

21 Nov '13

Just an update: All feature requests which did not have a devel owner were moved to a separate sheet. From experience, not all features with a devel owner make the version, and some more items will probably get devel owners over the next couple of weeks. Thanks, itamar

[Users] info on chrome and spice
by Gianluca Cecchi 21 Nov '13

21 Nov '13

Hello, I have an all-in-one installation based on Fedora 18 and oVirt stable repo. oVirt is 3.2.3-1.fc18 Fedora system is updated at 11/11/2013. I have both firefox (firefox-25.0-3.fc18.x86_64) and chrome (google-chrome-stable-30.0.1599.114-1.x86_64 , baseurl of yum from baseurl=http://dl.google.com/linux/chrome/rpm/stable/x86_64) While I can use spice console with firefox, in chrome the icon is not enabled. Is there any way to have chrome able to open spice console? Does it change anything in oVirt 3.3 for chrome on Linux (and/or on WIndows)? Thanks, Gianluca

[Users] replacing self-signed certificates
by i iordanov 21 Nov '13

21 Nov '13

Hello, I searched around but could not come up with specific instructions for how to replace the self-signed certificates in an oVirt 3.3 setup with non-self-signed certificates. I need to ensure that my oVirt/SPICE client actually does the right thing when connecting to a machine with a 3rd party signed certificate. Presumably, I would be able to adapt the instructions provided here: http://www.ovirt.org/How_to_change_engine_host_name right? Which steps need to be modified? If I hammer at it long enough, I would probably succeed in getting it to work at some point, but I was hoping for somebody more experienced to help me over the initial hurdle. In case I have to reinstall to use non-self-signed certificates, how do I go about preparing the environment prior to running engine-setup? Thanks! iordan -- The conscious mind has only one thread of execution.

[Users] RFE question
by Jakub Bittner 21 Nov '13

21 Nov '13

Hello, I would like to ask how to post RFE to oVirt. I know about google spreadsheet, but should I post RFE to users mailing list and after some discussion post it to bugzilla? I have 2 rfe on oVirt web interface: 1) I think that nice to have feature would be to have fourth column with disk usage in Virtual Machine tab. 2) Great improvement wold also be possibility to sort Virtual Machine tab by clicking on column name. For example: When I click on "Memory" all VMs get sorted by memory usage. If this RFE already exists, I am sorry. But I did not find it. Thank you.

[Users] Problem with host
by Koen Vanoppen 20 Nov '13

20 Nov '13

Hello All, I was a little bit to enthusiastic and removed a Test-Datacenter with 1 test cluster and 1 host in it. Now I have these error messages (but the host doesn't exist anymore) : Host apollo01 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" Alerts (2) Events Tasks (0) 2013-Nov-19, 10:37 Host apollo01 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" And on top of that, I can't re-add the host, because oVirt still things he is present.. Anybody knows a solution to this issue? Kind Regards, Koen
