I understand syncing virtual disk state with the OS cache is a quite challenge to a snapshot tool developers. However, it is a handy feature for the users just want to back up their data in the disks without stopping VM. As other virtualization solution support this feature, we should narrow the gap to attract more users to oVirt. > > Thanks, > michal > > On 27 Jun 2012, at 17:26, Shu Ming <shuming(a)linux.vnet.ibm.com> wrote: > >> On 2012-6-27 23:19, Dafna Ron wrote: >>> Hi, >>> >>> no. the snapshot is for the entire vm and it's disks. >>> >>> >>> On 06/27/2012 05:31 PM, Shu Ming wrote: >>>> Hi, >>>> >>>> I am testing oVirt engine 3.1 beta release 06-07.

[Users] How can I create a snapshot for virtual disks only?
by Shu Ming 27 Jun '12

27 Jun '12

Hi, I am testing oVirt engine 3.1 beta release 06-07. I tried "snapshots-->create" button for a VM and it looked like that the snapshot to be created was for both the running state of the system and the virtual disks. I am wondering if there is any way to create the snapshot only for the virtual disks of the VM in engine? -- Shu Ming <shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory

[Users] What is the best way to debug a VDSM hook?
by Robert Middleswarth 26 Jun '12

26 Jun '12

I installed the hook smbios but it doesn't seem to be working. I was told earlier I needed to create a custom property to pass the data but that doesn't seem to be working. Not sure what I am doing wrong. I am looking for debugging hints on how to show what is being passed to the hook to confirm it is grabbing the correct info and what is being passed back to vdsm? http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=tree;f=vdsm_hooks/smbios;h=c61c… Thanks Robert

[Users] Two updates from the oVirt team
by Ofer Schreiber 26 Jun '12

26 Jun '12

Hey everyone, There are two updates I'd like to share with you: 1. oVirt 3.1 release date has been delayed to the 9th of July. As you all know, We're in the middle of creating a new build of oVirt. With your help, we found multiple issues which we consider as release blockers. Some of these issues require a few days to be solved properly, and as a result, we had to delay the general availability of oVirt. 2. New ovirt-engine rpms are available for download at http://ovirt.org/releases/beta/fedora/17 This build contain multiple bug fixes, as well as a new versioning schema, which will ensure future updates will be done correctly. Please note, that due to the new versions, we don't support in-beta upgrade. please make sure you clean up you environment (using engine-cleanup, and yum remove) before installing the new rpms (version 3.1.0-0.1.20120620git6ef9f8.fc17) New VDSM rpms should be available in the beginning of next week). Regards, -- Ofer Schreiber oVirt Release Manager

[Users] Unable to add iSCSI storage domain - 3.1 beta
by Trey Dockendorf 25 Jun '12

25 Jun '12

I'm attempting to add iSCSI storage to a data center via web interface, and while I"m able to see the target ISCSI device and login, clicking the "OK" button doesn't submit the storage selection. I noticed from looking at the oVirt manual that somewhere in this interface I have to select the LUN. However once logged into the target I never see LUNs to select. I've attached two screenshots that show the UI and what could be errors in how it's being displayed. I also attached logs from vdsm host and engine that were captured while attempting to add the storage domain. After logging into the iSCSI target via web interface, this is the output on target host, showing that my ovirt node (10.20.1.240) is connected. # tgtadm --lld iscsi --op show --mode target Target 1: iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool System information: Driver: iscsi node dc-store0.tamu.edu State: ready I_T nexus information: I_T nexus: 3 Initiator: iqn.1994-05.com.redhat:ad499aa5f37e Connection: 0 IP Address: 10.20.1.240 LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: p_lu_coraid23_lu SCSI SN: (stdin)= Size: 4398047 MB, Block size: 512 Online: Yes Removable media: No Readonly: No Backing store type: rdwr Backing store path: /dev/vg_coraid23/lv_kvm_pool Backing store flags: Account information: ACL information: ALL Based on some archived emails I've included previously mentioned outputs that may help >From the ovirt node: # iscsiadm -m discovery -p 10.20.1.250 -t sendtargets --login 10.20.1.250:3260,1 iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool Logging in to [iface: default, target: iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool, portal: 10.20.1.250,3260] (multiple) Login to [iface: default, target: iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool, portal: 10.20.1.250,3260] successful. # multipath -r Jun 25 14:19:22 | 3600508e0000000004ecf45ecb0c2ec0a: ignoring map reload: 1p_lu_coraid23_lu undef IET,VIRTUAL-DISK size=4.0T features='0' hwhandler='0' wp=undef `-+- policy='round-robin 0' prio=1 status=undef `- 8:0:0:1 sdc 8:32 active ready running # iscsiadm -m session tcp: [4] 10.20.1.250:3260,1 iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool # vdsClient -s 0 getDeviceList [{'GUID': '1p_lu_coraid23_lu', 'capacity': '4398046511104', 'devtype': 'iSCSI', 'fwrev': '0001', 'logicalblocksize': '512', 'partitioned': False, 'pathlist': [{'connection': '10.20.1.250', 'initiatorname': 'default', 'iqn': 'iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool', 'port': '3260', 'portal': '1'}], 'pathstatus': [{'lun': '1', 'physdev': 'sdc', 'state': 'active', 'type': 'iSCSI'}], 'physicalblocksize': '512', 'productID': 'VIRTUAL-DISK', 'pvUUID': '7MHtfm-352q-zWrT-KfU8-sJ1l-e4rP-aKsuhu', 'serial': 'SIET_VIRTUAL-DISK', 'vendorID': 'IET', 'vgUUID': 'YCso68-YCo8-w817-I5Nf-mFx3-aoPe-LWkYco'}] # vgs -o+pv_name VG #PV #LV #SN Attr VSize VFree PV f18b2342-4713-4319-a878-3025b38556a4 1 6 0 wz--n- 4.00t 4.00t /dev/mapper/1p_lu_coraid23_lu vg_dc-kvm0 1 2 0 wz--n- 67.50g 0 /dev/sda2 Thanks - Trey

[Users] Following Up on LinuxCon Japan Workshop
by Leslie Hawthorn 25 Jun '12

25 Jun '12

Hello everyone, I'd like to collect feedback from everyone on last week's oVirt workshop at LinuxCon Japan. [0] Please reply back with comments by close of business this Friday, 15 June. Once we have gathered feedback on list, I'll capture it on the oVirt wiki. We can then use what we've learned to help construct the agenda and other plans for other upcoming oVirt workshops at LinuxCons. [1] If you know that you would like to volunteer as an instructor for future workshops or would like to suggest alternate content for the workshop, please include that in your feedback. - Course Material What sessions were most well received? Which ones require improvement? Any additional sessions we'd suggest? - Audience Participation How many attendees? How did the Q&A periods go? Would we like to prepare a post-event attendee survey? (I recommend we do the survey and can prepare some questions for the group if that's useful.) - Developer/user traction resulting from engaging at workshop Did this workshop help us to gain new developers or users? Reinforce relationships with existing community members? - Promotion of the event, both before and after What could be done to more effectively promote the event prior to the workshops? Videos and slides from the workshop should be posted on the LC Japan site tomorrow; what action would the community like to take to promote this content? - A/V and Room Set up Did the seating arrangements work well for the workshop format? Did the A/V work well, including the videotaping process? - Food and beverage Did the catered in lunch help to keep the flow of the workshop productive? Was the food of good quality and in keeping with the needs of attendee dietary constraints? - Give aways We did not produce attendee gifts for the oVirt workshop. Thoughts on whether this would be a welcome addition in the future? Suggestions for type of gift also welcome. - Any other feedback If it is preferable to discuss this feedback real-time, I will ask Mike Burns to give us more time for this topic during next week's oVirt IRC meeting.
