Re: [External] : Re: about the hugepage setting of the KVM server
by Tommy Sway 01 Sep '21

I use the ovirt-node, and I configured HUGEPAGE on the VM, and does not configure the HUGEPAGE on the KVM host. The THP I don't configure anything about it, and after configure the HUGEPAGE on the vm, there is no report. I don't know which method is the best.

Unable to export VM from data storage domain.
by Diggy Mc 01 Sep '21

01 Sep '21

I'm running oVirt 4.4.4 with two data storage domains. One domain is where the production VMs run. The second domain is where I make backup copies of the VMs in the event of problems with the main production VMs. I make backups using the export option from the GUI's dropdown list. I just now tried to "restore" a backup copy via the export function and get an error. In fact, I get errors trying to export (import to my original data domain) any of the VMs that were exported to my backup data domain. My backup domain is a DATA domain and not an EXPORT domain. The exact error is: Export VM Failed [Cannot add VM. Cannot find a disk profile defined on storage domain 246c69e9-6f16-489f-8022-8613f6c1c22a.] Is this a bug or am I doing something wrong? Help is needed urgently. In advance, thank you.

I have tried exporting 4 VMs (2 centos and 2 Windows) to an nfs mount (export OVA) and importing from ova and I can't see all the files.

Re: How to re-import a VM with an invalid timezone?
by Saif Abu Saleh 31 Aug '21

31 Aug '21

Hi, Can you please provide what time-zone the VM you are trying to Import has? if you are trying to import from the OVA you can get the time-zone by going to the host location where the exported OVA exists, open it and check what is the value of the <TimeZone> tag Thanks, Saif From: <hibbsncc1701(a)gmail.com> > Date: Fri, Aug 27, 2021 at 9:27 AM > Subject: [ovirt-users] How to re-import a VM with an invalid timezone? > To: <users(a)ovirt.org> > > > I've just finished my upgrade to oVirt 4.4.8.4, but I've got one > previously working VM that I cannot reimport.

Crash Debugging VDSM Hook
by Jean-Louis Dupond 31 Aug '21

31 Aug '21

Hi All, While debugging some Qemu 6 issue I was requested to remove the error_policy from the libvirt xml. See https://bugzilla.redhat.com/show_bug.cgi?id=1999051#c12 Now to have this working I just wrote some small python hook for VDSM which adjusts the XML before startup. Just added the file in /usr/libexec/vdsm/hooks/before_vm_start: # cat 40_crashtest #!/usr/libexec/platform-python import os import hooking class CrashTestHook(object): def __init__(self): super(CrashTestHook, self).__init__() self.config = {} self.domxml = hooking.read_domxml() def save(self): hooking.write_domxml(self.domxml) def set_error_policy(self): drivers = self.domxml.getElementsByTagName('driver') for driver in drivers: policy = driver.getAttribute('error_policy') if policy == 'stop': driver.removeAttribute('error_policy') def main(self): self.set_error_policy() self.save() if __name__ == "__main__": CrashTestHook().main() # vim: expandtab tabstop=4 shiftwidth=4 Might be usefull if somebody else needs the same thing :) Jean-Louis
