Fail to upgrade cluster from 4.3 to 4.4

by Gianluca Cecchi

Hello, my environment was oVirt 4.3.10 with an external engine and 3 hosts. I have updated to 4.4.3 the whole infra, but know if I go and update the cluster to 4.4 I get the message in this window: https://drive.google.com/file/d/1hfs4FC8uZ-EjiCzQyitA3945U0Knnz2m/view?us... What is the reason for it? My Cluster is with Cluster CPU Type: "Intel Westmere IBRS SSBD Family" The signalled 'hostmaster' VM is a powered off VM used in the past to test nested virtualization and in "Virtual Machines" page aside it I see an exclamation mark with "The VM CPU doesn't match the Cluster Cpu Type" The VM is set as custom, optimized for Server Custom Chipset/Firmware Type "Cluster default (i440FX Chipset with BIOS)" Custom Emulated Machine (in grey): "Cluster default(pc-i440fx-rhel7.6.0)" Custom CPU (in grey): "Cluster default(Intel Westmere IBRS SSBD Family)" What I'm expected to change? Thanks, Gianluca

Network profile filtering

by pascal＠butterflyit.com

I am using ovirt 4.3. I am in need to isolate all my VM from each other (without using VLAN) except to a virtual gateway which is also the DHCP server. Basically only allowing traffic from 1 MAC address to another MAC address. Everything else should be filter out by ovirt filtering subsystem How will I go about that? I can see in network profile the ability to set different filter but can't find a way to create new filter. Thanks for your help Pascal

Unable to attach VLAN-based logical networks to a bond oVirt 4.4

by simon＠justconnect.ie

When attempting to add a VLAN to a bonded interface (Broadcom NICs) in oVirt Management portal the process fails as per: https://bugzilla.redhat.com/show_bug.cgi?id=1860479 This issue has rendered mu upgrade to 4.4 useless. Does anyone have a patched kernel to resolve this please? Regards Shimme

Ballooning disabled when creating a VmPool

by Nicolás

Hi, We're using oVirt 4.3.8 along with ovirt-engine-sdk-python (4.4.1) to handle our pools. Pools are based on a template which has ballooning enabled. However, when deploying a VmPool based on that template, has the "Ballooning enabled" field disabled, uneditable and an icon which states: "The field is not attached to any instance type" (screenshot attached). We're handling a big number of VMs based on pools (> 1500), and we think this should be enabled. However, I don't see a field in the types.VmPool definition that allows that. Is that even doable? Our Python code is similar to this: newpool = types.VmPool(name='test', cluster=cl, template=t, max_user_vms=1, size=1, type=types.VmPoolType.MANUAL) vmpool_serv.add(newpool) * cl is a types.Cluster instance with ballooning_enabled=True * t is a types.Template instance with Ballooning enabled. Thanks. Nico

Old and new hardware mix

by nick＠creativitysoftware.net

Hi All, I've just joined the mailing list as my organisation needs a new virtualisation solution. VMware is prohibitively expensive for a small company like ours and of all the opensource solutions, oVirt looks like the best fit for our needs. Our existing virtual infrastructure is primarily made up of an old vSphere 5 cluster (expired license on old and out of warranty hardware) and a couple of newer standalone (free) ESXi servers. Both the cluster and the standalones have shared NFS storage so I can move VMs around. I want to take a couple of older (2014ish) servers which will serve as the management host and one compute node initially. Then, I'd like to migrate VMs from one vSphere host at a time to the newly created oVirt cluster and convert the now empty vSphere ESXi hosts into oVirt compute nodes as I go. Firstly - Would new compute host hardware (2020) work in a (2014) based ovirt cluster? If so Would I be able to take advantage of the more advanced features of ovirt like live migration etc.. with a mix of new and old hardware Thanks

Re: sshd_config AuthorizedKeysFile

by Strahil Nikolov

What happens when you change the default, but also add a "Match" directive overriding that option for the engine ? Best Regards, Strahil Nikolov В четвъртък, 12 ноември 2020 г., 10:01:12 Гринуич+2, Angus Clarke <angus(a)charworth.com> написа: Hello Sharing for anyone who needs it, this was carried out on OL7, they use ovirt 4.3 In short: both the hosted-engine deployment routine and the host add to cluster routine distribute public ssh keys to /root/.ssh/authorized_keys regardless of the AuthorizedKeysFile setting in /etc/ssh/sshd_config. Both routines fail if AuthorizedKeysfile is not default. The hosted-engine setup assumes AuthorizedKeysFile to be default (~/.ssh/authorized_keys) and creates a public key there, instead of following the sshd_config directive. The setup fails on the back of this. Once I commented this out of sshd_config file (assumes default) and restarted sshd on the KVM host that was running the hosted-engine deployment, the hosted-engine setup completed successfully. Similarly, I could not deploy a second KVM host to the compute cluster until I had altered this setting on that 2nd KVM host - presumably that process has some similar routine that unwittingly writes keys to ~/.ssh/authorized_keys.HTH Angus _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/UMJ4Y622RAL...

rhv 4.3.11 but not ovirt 4.3.11

by Gianluca Cecchi

Hello, I see that a 4.3.11 version is available for downstream RHV but not for upstream oVirt. Will it be released for oVirt too? Are there only security fixes inside or also bug fixes (like the few lines one related to export as OVA)? Thanks, Gianluca
