Bcp vm
by Ali Gusainov
Hello experts.
Environment:
2 identical servers running
CentOS Linux release 7.7.1908
oVirt Version:4.3.7.2-1.el7
No clusters configured.
NFS share for backups on third server.
Have some questions.
1. Need to create backups of virtual machines to NFS without downtime. Can an 'OVA export' be a complete policy for backups?
2. Is there a way to export vm to OVA via command line?

VDSM certs expired, manual renewal not working
by cen
Hi
Our VDSM certs have expired, both hosts are unassigned and can't be put
into maintenance from UI.
vdsm-client is not working, times out even with --insecure flag. Does
host and port need to be specified when run locally or should defaults work?
Error in console events is: Get Host Capabilities Failed: PKIX path
validation failed...
I followed a RHV guide for this exact situation and generated new vdsm
certificate using the ovirt-engine CA.
The new cert seems identical to the old one, everything matches (algos,
extensions, CA, CN, SAN etc) just new date.
After restarting libvirtd and vdsmd on the host with new cert in place
the host is still not reachable.
However, error message is now slightly different:
get Host Capabilities failed: Received fatal error: certificate_expired
Cert was replaced in the following locations:
/etc/pki/vdsm/certs/vdsmcert.pem
/etc/pki/vdsm/libvirt-spice/server-cert.pem
/etc/pki/libvirt/clientcert.pem
Is there another location missing? What else can I try?
All help appreciated in advance

/tmp/lvm.log keeps growing in Host
by kanehisa＠ktcsp.net
I don't understand why lvm.log is placed in /tmp directory without rotation.
I noticed this fact when I got the following event notification every 2 hours.
EventID ：24
Message ：Critical, Low disk space. Host ovirt01 has less than 500 MB of free space left on: /tmp. Low disk space might cause an issue upgrading this host.
As a workaround, I added a log rotation setting to /tmp/lvm.log, but is this the correct way?
I should have understood the contents of the Python program below before asking the question,
but please forgive me because I am not very knowledgeable about Python.
# cat /usr/lib/python3.6/site-packages/blivet/devicelibs/lvm.py | grep lvm.log
config_string += "log {level=7 file=/tmp/lvm.log syslog=0}"
Thanks in advance!!

virt-viewer - working alternative
by lars.stolpe＠bvg.de
Hi all,
i tryed to use virt-viewer 11 (Windows) with oVirt 4.4 . I also tryed virt-viewer 10, 9, 8, and 7.
The older versions can't handle ISO residing in data domains, the latest version is crashing if try the media button.
Almost all links on the website are dead, no user guide, no prerequisites list...
Since virt-viewer is not working properly and seems to be abandoned, i'm looking for a working alternative.
Is there a working way to get a console of the virtual machines running in oVirt 4.4?

4.4.9 -> 4.4.10 Cannot start or migrate any VM (hotpluggable cpus requested exceeds the maximum cpus supported by KVM)
by Jillian Morgan
After upgrading the engine from 4.4.9 to 4.4.10, and then upgrading one
host, any attempt to migrate a VM to that host or start a VM on that host
results in the following error:
Number of hotpluggable cpus requested (16) exceeds the maximum cpus
supported by KVM (8)
While the version of qemu is the same across hosts, (
qemu-kvm-6.0.0-33.el8s.x86_64), I traced the difference to the upgraded
kernel on the new host. I have always run elrepo's kernel-ml on these hosts
to support bcache which RHEL's kernel doesn't support. The working hosts
still run kernel-ml-5.15.12. The upgraded host ran kernel-ml-5.17.0.
In case anyone else runs kernel-ml, have you run into this issue?
Does anyone know why KVM's KVM_CAP_MAX_VCPUS value is lowered on the new
kernel?
Does anyone know how to query the KVM capabilities from userspace without
writing a program leveraging kvm_ioctl()'s?
Related to this, it seems that ovirt and/or libvirtd always runs qmu-kvm
with an -smp argument of "maxcpus=16". This causes qemu's built-in check to
fail on the new kernel which is supporting max_vpus of 8.
Why does ovirt always request maxcpus=16?
And yes, before you say it, I know you're going to say that running
kernel-ml isn't supported.
