[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.

Merge rights changes in the oVirt Engine project
by Tal Nisan 09 Apr '21

09 Apr '21

Hi everyone, As you probably know we are now in a mode in which we develop our next zstream version on the master branch as opposed to how we worked before where the master version was dedicated for the next major version. This makes the rapid changes in master to be delivered to customers in a much higher cadence thus affecting stability. Due to that we think it's best that from now on merges in the master branch will be done only by stable branch maintainers after inspecting those closely. What you need to do in order to get your patch merged: - Have it pass Jenkins - Have it get code review +2 - Have it mark verified +1 - It's always encourage to have it tested by OST, for bigger changes it's a must Once you have all those covered, please add me as a reviewer and I'll examine it and merge if everything seems right, if I haven't done it in a timely manner feel free to ping me.

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

CentOS Stream support
by Michal Skrivanek 01 Feb '21

01 Feb '21

Hi all, we would like to ask about interest in community about oVirt moving to CentOS Stream. There were some requests before but it’s hard to see how many people would really like to see that. With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS. So..would you like us to support CentOS Stream? We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS? There are some concerns about Stream being a bit less stable, do you share those concerns? Thank you for your comments, michal

Possible i18n for cockpit-ovirt ?
by Juliette Tux 23 Sep '20

23 Sep '20

Hello, Localizator/translator here :) I have a small question regarding the cockpit-ovirt utility[1]. Are there any plans of adding the i18n into the code to facilitate proper translation of cockpit-ovirt? Thank you!

device compatibility interface for live migration with assigned devices
by Yan Zhao 15 Sep '20

15 Sep '20

hi folks, we are defining a device migration compatibility interface that helps upper layer stack like openstack/ovirt/libvirt to check if two devices are live migration compatible. The "devices" here could be MDEVs, physical devices, or hybrid of the two. e.g. we could use it to check whether - a src MDEV can migrate to a target MDEV, - a src VF in SRIOV can migrate to a target VF in SRIOV, - a src MDEV can migration to a target VF in SRIOV. (e.g. SIOV/SRIOV backward compatibility case) The upper layer stack could use this interface as the last step to check if one device is able to migrate to another device before triggering a real live migration procedure. we are not sure if this interface is of value or help to you. please don't hesitate to drop your valuable comments. (1) interface definition The interface is defined in below way: __ userspace /\ \ / \write / read \ ________/__________ ___\|/_____________ | migration_version | | migration_version |-->check migration --------------------- --------------------- compatibility device A device B a device attribute named migration_version is defined under each device's sysfs node. e.g. (/sys/bus/pci/devices/0000\:00\:02.0/$mdev_UUID/migration_version). userspace tools read the migration_version as a string from the source device, and write it to the migration_version sysfs attribute in the target device. The userspace should treat ANY of below conditions as two devices not compatible: - any one of the two devices does not have a migration_version attribute - error when reading from migration_version attribute of one device - error when writing migration_version string of one device to migration_version attribute of the other device The string read from migration_version attribute is defined by device vendor driver and is completely opaque to the userspace. for a Intel vGPU, string format can be defined like "parent device PCI ID" + "version of gvt driver" + "mdev type" + "aggregator count". for an NVMe VF connecting to a remote storage. it could be "PCI ID" + "driver version" + "configured remote storage URL" for a QAT VF, it may be "PCI ID" + "driver version" + "supported encryption set". (to avoid namespace confliction from each vendor, we may prefix a driver name to each migration_version string. e.g. i915-v1-8086-591d-i915-GVTg_V5_8-1) (2) backgrounds The reason we hope the migration_version string is opaque to the userspace is that it is hard to generalize standard comparing fields and comparing methods for different devices from different vendors. Though userspace now could still do a simple string compare to check if two devices are compatible, and result should also be right, it's still too limited as it excludes the possible candidate whose migration_version string fails to be equal. e.g. an MDEV with mdev_type_1, aggregator count 3 is probably compatible with another MDEV with mdev_type_3, aggregator count 1, even their migration_version strings are not equal. (assumed mdev_type_3 is of 3 times equal resources of mdev_type_1). besides that, driver version + configured resources are all elements demanding to take into account. So, we hope leaving the freedom to vendor driver and let it make the final decision in a simple reading from source side and writing for test in the target side way. we then think the device compatibility issues for live migration with assigned devices can be divided into two steps: a. management tools filter out possible migration target devices. Tags could be created according to info from product specification. we think openstack/ovirt may have vendor proprietary components to create those customized tags for each product from each vendor. e.g. for Intel vGPU, with a vGPU(a MDEV device) in source side, the tags to search target vGPU are like: a tag for compatible parent PCI IDs, a tag for a range of gvt driver versions, a tag for a range of mdev type + aggregator count for NVMe VF, the tags to search target VF may be like: a tag for compatible PCI IDs, a tag for a range of driver versions, a tag for URL of configured remote storage. b. with the output from step a, openstack/ovirt/libvirt could use our proposed device migration compatibility interface to make sure the two devices are indeed live migration compatible before launching the real live migration process to start stream copying, src device stopping and target device resuming. It is supposed that this step would not bring any performance penalty as -in kernel it's just a simple string decoding and comparing -in openstack/ovirt, it could be done by extending current function check_can_live_migrate_destination, along side claiming target resources.[1] [1] https://specs.openstack.org/openstack/nova-specs/specs/stein/approved/libvi… Thanks Yan

[ARM64] Possiblity to support oVirt on ARM64
by Zhenyu Zheng 11 Sep '20

11 Sep '20

Hi oVirt, We are currently trying to make oVirt work on ARM64 platform, since I'm quite new to oVirt community, I'm wondering what is the current status about ARM64 support in the oVirt upstream, as I saw the oVirt Wikipedia page mentioned there is an ongoing efforts to support ARM platform. We have a small team here and we are willing to also help to make this work. Thanks alot, Zhenyu Zheng
