[VDSM] Started getting virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired
by Edward Haas 11 Jan '24

11 Jan '24

Hi, I have a VM which acts as an oVirt host with VDSM installed. I use it for testing without connecting it to Engine. Recently VDSM fails to come up and I see this error: Sep 26 17:58:18 localhost libvirtd: 2018-09-26 14:58:18.978+0000: 12176: error : virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired Any hint on how to generate or fetch a new certificate without the help of Engine? Thanks, Edy.

I want to remove inactive contributors from vdsm-master-maintainers. I suggest the simple rule of 2 years of inactivity for removing from this group, based on git log. See the list below for current status: https://gerrit.ovirt.org/#/admin/groups/106,members Thoughts? Nir

Error Java SDK Issue??
by Geschwentner, Patrick 02 Apr '21

02 Apr '21

Dear Ladies and Gentlemen! I am currently working with the java-sdk and I encountered a problem. If I would like to retrieve the disk details, I get the following error: Disk currDisk = ovirtConnection.followLink(diskAttachment.disk()); The Error is occurring in this line: [cid:image001.png@01D44537.AF127FD0] The getResponst looks quiet ok. (I inspected: [cid:image002.png@01D44537.AF127FD0] and it looks ok). Error: wrong number of arguments The code is quiet similar to what you published on github (https://github.com/oVirt/ovirt-engine-sdk-java/blob/master/sdk/src/test/jav… ). Can you confirm the defect? Best regards Patrick

If not, you should edit 'upload_disk_snapshot.py' to add a variable 'vm_id'(as variable sd_name in this script) to attach the uploaded disk. I agree. It would be nice if we can do: $ mkdir -p backups/vm-id $ download_disk_snapshots.py --backup-dir backups/vm-id ... $ upload_disk_snapshots.py --backup-dir backups/vm-id ... download_disk_snapshots.py will download vm ovf and all disks. upload_disk_snaphsots.py would take the output of download_disk_snapshots.py and create a new vm. > I suppose that the best thing is to discard the gerrit, and to propose first what you want with 'download_disk_snapshot.py' and 'upload_disk_snapshot.py' and then act accordingly (several patch). Do you agree? This is a bigger change that can take more time. I think we better fix the issues in the current scripts - the first one is the missing attach disk that you fix in your patch. Since you posted this fix with a lot of other unrelated fixes (some wrong or unneeded), we cannot merge it. This is another reason to post minimal patches that do one fix. > I'm only truly interested in opened bug with block domain and volumes of > 1GB: https://bugzilla.redhat.com/show_bug.cgi?id=1707707. I make these changes to help a little since you would help me by solving the bug. I don't code in Python, I code in Java, using Java-sdk and the bug is a major limitation in my software, so I want resolve this bug (1 year old). =( I hope you understand. :) Sure, I understand. If you don't time to work on this, some other developer can take over this patch. The bug should be fixed by: https://gerrit.ovirt.org/c/108991/ It would be nice if you can test this. I started a build here: https://jenkins.ovirt.org/job/ovirt-engine_standard-check-patch/5867/ When the build is ready, you will be able to install engine from this build by adidng a yum repo with the baseurl: https://jenkins.ovirt.org/job/ovirt-engine_standard-check-patch/5867/artifa… Note that this requires CentOS 8.1. If you want to test on CentOS 7, you need to wait until the fix will be backported to 4.3, or since you like Java, maybe port it yourself? Note also that we have a much more advanced backup and restore options: https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_v… Here is example run I did yesterday: I started with full backup of a running vm: $ ./backup_vm.py full --engine-url https://engine3/ --username admin@internal --password-file /home/nsoffer/.config/ovirt/engine3/password --cafile /home/nsoffer/Downloads/certs/engine3.pem --backup-dir /home/nsoffer/tmp/backups/test-nfs b5732b5c-37ee-4c66-b77e-bda5d37a10fe [ 0.0 ] Starting full backup for VM b5732b5c-37ee-4c66-b77e-bda5d37a10fe [ 1.5 ] Waiting until backup f73541c6-88d1-4dac-a551-da922cdb3f55 is ready [ 4.6 ] Created checkpoint '4754dc34-da4b-4e62-84ea-164c413b003c' (to use in --from-checkpoint-uuid for the next incremental backup) [ 4.6 ] Creating image transfer for disk 566e6aa6-575b-4f83-88c9-e5e5b54d9649 [ 5.9 ] Waiting until transfer 98e5aabc-fedb-4d2c-81c5-eed1a8b07790 will be ready [ 5.9 ] Image transfer 98e5aabc-fedb-4d2c-81c5-eed1a8b07790 is ready [ 5.9 ] Transfer url: https://host4:54322/images/13a0a396-5070-4b0f-a5cd-e2506c5abf0f Formatting '/home/nsoffer/tmp/backups/test-nfs/566e6aa6-575b-4f83-88c9-e5e5b54d9649.202005132336.full.qcow2', fmt=qcow2 size=6442450944 cluster_size=65536 lazy_refcounts=off refcount_bits=16 [ 100.00% ] 6.00 GiB, 18.34 seconds, 334.95 MiB/s [ 24.3 ] Finalizing transfer 98e5aabc-fedb-4d2c-81c5-eed1a8b07790 [ 24.5 ] Full backup completed successfully This downloads all vms disks to ~/tmp/backups/test-nfs/, creating 566e6aa6-575b-4f83-88c9-e5e5b54d9649.202005132336.full.qcow2 This file includes entire disk content at the time the backup was stated.

Resolve IPv6 hostname inside vdsm-gluster
by Kaustav Majumder 28 May '20

28 May '20

Hi devel, Is it possible to resolve an IPv6 address from a hostname inside VDSM? I am aware of socket.getaddrinfo <https://docs.python.org/3.8/library/socket.html#socket.getaddrinfo>, but are there any libs inside vdsm which already does it, and I can use. What do I want to do with it? For this command inside VDSM *gluster vol info <volname> --remote-host=host1.test.example.com <http://host1.test.example.com>* Gluster is not able to resolve the ip of host1.test.example.com and fails as https://pastebin.com/Bt1AUvkU. I wanted to know if a workaround can be added in vdsm-gluster to resolve a static IPv6 host and pass the ip to the gluster command. -- Thanks, Kaustav Majumder

Cant get Sysprep to insert product key in Win2016 guest on RHV 4.3
by Lynn Dixon 24 May '20

24 May '20

I am trying to create a basic Windows server 2016 template in RHV 4.3 . I've installed the OS from the Windows DVD, and installed all the RHV tools, and drivers. Then I do a sysprep on my windows VM and make a template from it. I'd like to inject the product key when the template is cloned. I thought if we define the product key in /etc/ovirt-engine/osinfo.conf.d/10-productkeys.properties. with something like this: # Windows2016x64(29, OsType.Windows, true); os.windows_2016x64.id.value = 29 os.windows_2016x64.name.value = Windows 2016 x64 os.windows_2016x64.derivedFrom.value = windows_2012R2x64 os.windows_2016x64.cpu.unsupported.value = conroe, penryn, nehalem, opteron_g1 os.windows_2016x64.sysprepPath.value = ${ENGINE_USR}/conf/sysprep/sysprep.2k16x64 os.windows_2016x64.productKey.value = MY-WIN-PRODUCT-KEY That it would insert the product key when we tick the "Cloud Init / Sysprep" box on the run-once dialog. Now, I know this is semi-working, because all the other things I define in the run-once dialog after clicking sysprep works: Admin password, hostname, etc. But NOT the product key! I have even tried hard coding the product key in the sysprep.2k16x64 file and no luck. What am I doing wrong here? *Lynn Dixon* | Red Hat Certified Architect #100-006-188 *Solutions Architect* | NA Commercial Google Voice: 423-618-1414 Cell/Text: 423-774-3188 Click here to view my Certification Portfolio <http://red.ht/1XMX2Mi>
