We have more USB devices redir (There are 8)，But oVirt supports only 6. How should I configure it. /etc/engine-config/engine-config.properties NumberOfUSBSlots.validValues=0..6 This 0..6 modify 0..8 engine-config -s NumberOfUSBSlots=8 engine-config -g NumberOfUSBSlots NumberOfUSBSlots: 8 version: general But No entry into force Should I do？ Thanks

OVIRT 4.2: MountError on Posix Compliant FS
by jtorres＠bsc.es 19 Jul '18

19 Jul '18

Hi all, I've deployed the ovirt Version 4.2.4.5-1.el7 on a small cluster and I'm trying to use as datastorage domain a configured Spectrum Scale (GPFS) distributed filesystem for test it. I've completed the configuration of the storage, and the filesystem defined are correctly mounted on the client hosts as we can see: gpfs_kvm gpfs 233T 288M 233T 1% /gpfs/kvm gpfs_fast gpfs 8.8T 5.2G 8.8T 1% /gpfs/fast The content output of the mount comand is: gpfs_kvm on /gpfs/kvm type gpfs (rw,relatime) gpfs_fast on /gpfs/fast type gpfs (rw,relatime) I can write and read to the mounted filesystem correctly, but when I try to add the local mounted filesystem I encountered some errors related to the mounting process of the storage. The parameters passed to add new storage domain are: Data Center: Default (V4) Name: gpfs_kvm Description: VM data on GPFS Domain Function: Data Storage Type: Posix Compliant FS Host to Use: kvm1c01 Path: /gpfs/kvm VFS Type: gpfs Mount Options: rw, relatime The ovirt error that I obtained is: Error while executing action Add Storage Connection: Problem while trying to mount target On the /var/log/vdsm/vdsm.log I can see: 2018-07-05 09:07:43,400+0200 INFO (jsonrpc/0) [vdsm.api] START connectStorageServer(domType=6, spUUID=u'00000000-0000-0000-0000-000000000000', conList=[{u'mnt_options': u'rw,relatime', u'id': u'00000000-0000-0000-0000-000000000000', u'connection': u'/gpfs/kvm', u'iqn': u'', u'user': u'', u'tpgt': u'1', u'vfs_type': u'gpfs', u'password': '********', u'port': u''}], options=None) from=::ffff:10.2.1.254,43908, flow_id=498668a0-a240-469f-ac33-f8c7bdeb481f, task_id=857460ed-5f0e-4bc6-ba54-e8f2c72e9ac2 (api:46) 2018-07-05 09:07:43,403+0200 INFO (jsonrpc/0) [storage.StorageServer.MountConnection] Creating directory u'/rhev/data-center/mnt/_gpfs_kvm' (storageServer:167) 2018-07-05 09:07:43,404+0200 INFO (jsonrpc/0) [storage.fileUtils] Creating directory: /rhev/data-center/mnt/_gpfs_kvm mode: None (fileUtils:197) 2018-07-05 09:07:43,404+0200 INFO (jsonrpc/0) [storage.Mount] mounting /gpfs/kvm at /rhev/data-center/mnt/_gpfs_kvm (mount:204) MountError: (32, ';mount: wrong fs type, bad option, bad superblock on /gpfs/kvm,\n missing codepage or helper program, or other error\n\n In some cases useful info is found in syslog - try\n dmesg | tail or so.\n') I know, that from previous versions on the GPFS implementation, they removed the device on /dev, due to incompatibilities with systemd. I don't know if this change affect the ovirt mounting process. Can you help me to add this filesystem to the ovirt environment? The parameters that I used previously are ok? Or i need to do some modification? Its possible that the process fails because i dont have a device related to the gpfs filesystems on /dev? Can we apply some kind of workaround to mount manually the filesystem to the ovirt environment? Ex. create the dir /rhev/data-center/mnt/_gpfs_kvm manually and then mount the /gpfs/kvm over this? It's posible to modify the code to bypass some comprobations or something? Reading the available documentation over Internet I find that ovirt was compatible with this fs (gpfs) implementation, because it's POSIX Compliant, this is a main reason for test it in our cluster. It remains compatible on the actual versions? Or maybe there are changes that brokes this integration? Many thanks for all in advance! Kind regards!

Ovirt system crash when starting VM with Quadro GPU
by Wesley Stewart 18 Jul '18

18 Jul '18

I have recently been using an old Radeon R9 270X lying around without issue, until this card seemed to have kicked the bucket. I had an Nvidia Quadro P2000 lying around I thought I would try. After installing it into my system, it showed up in the PCI device as anticipated. I based both devices to my Windows 10 guest. It shows up a a GP106GL and a separate audio component. The same thing that happened with the AMD Radeon Card. The events just shows the VM's being terminated without giving a reason, and I am hoping for some guidance. Currently using a single node setup, running ovirt 4.2.3. Any ideas or places to check would be much appreciated!

Hi, We're using ovirt-engine-sdk-python 4.1.6 on oVirt 4.1.9, currently we're trying to delete some snapshots via a script like this: sys_serv = conn.system_service() vms_service = sys_serv.vms_service() vm_service = vms_service.vm_service(vmid) snaps_service = vm_service.snapshots_service() snaps_service.service('SNAPSHOT-ID').remove() This works, mostly... however, sometimes the deletion fails: Failed to delete snapshot 'snapshot name' for VM 'vm'. Is it currently possible to know via Python-SDK that the deletion actually failed? I know I can check the state of a snapshot, but I'd like to check the result of the task. Is that possible somehow? Thanks.

Windows VMs won't boot in debug mode
by Andrew X 17 Jul '18

17 Jul '18

Hi Everyone, I've been having problems getting Windows 10 VMs to boot in debug mode after turning on debugging over network (steps below). Also, device manager in Windows is not showing the processors' node which might be related (same reason why Windows is refusing to boot in debug mode?). I don't have any of these problems when I use generic KVM or Proxmox KVM. To turn on debugging in Windows, I do the follwoing from an admin terminal window: bcdedit /debug on bcdedit /dbgsettings net hostip:a.b.c.d port:p key:1.2.3.4 Any help will be appreciated, Thanks, Andrew
