Good afternoon everyone,
I have gotten my cloudstack running, but I am unable to live migrate any of my
VMs. I get an error like this: "Exception during migrate:
org.libvirt.LibvirtException: Cannot get interface MTU on 'brenp3s0f0-3128': No
such device"
I have tried using an L2, isolated, and
Hi!
Gabriel, could you suggest how to disable io_uring with agent.properties?
In the second lab, I turned off advanced virtualization repo and downgrade qemu
to native for CentOS 8 and everything works fine.
Generally, I use a lot of nested virtualization and I need the latest version
of qe
Hi Piotr,
Unfortunately, the current implementation does not allow to customize the
driver via the agent.properties.
Instead, it evaluates Libvirt and Qemu versions in order to assess if it is
supported.
I considered the libvirt & qemu documentation where address support for
io_uring and release
Hi Peter,
The information you provided is not enough to find out the root cause.
Could you share more information ?
cloudstack version
os distribution and version
network device name on source host and destination host
output of `brctl show` or `bridge link` on source host and destination host

Hi,
Thank you Gabriel for the explanations, being able to set up IO_Driver via
agent.properties is a good direction.
I will try to check why it is not supported in CentOS8 SIG Virtualization.
Regards,
Piotr

Hello devs
I am trying to integrate third party library into cloudstack but the
library supports @Configuration and @Enable* annotations to use it and not
with xml files.
I tried adding that annotation on a config file, built a new package but
the cloudstack wont boot.
It is stuck at below line
Sure.
Cloudstack version is 4.15.2
All of my systems are running Ubuntu server 20.04 (My hypervisor is KVM)
Yes, the network device names are different on the hosts (see below). this is
part of the issue, the virtual router does not seem to connect to the cloudbr1
or cloudbr0.
Host 1 interface t
I've found the problem, it wasn't a bug. It was a configuration issue.
I'm using 2 management servers with 2 database servers (HA) and HAProxy to
load balance access. My second management server was configured with an
error so it couldn't connect correctly with the database. When I created
some vi
Here are the agents' properties:

Cloudstack can migrate a VM after I shutdown the VM, so it can recognize it in
some way at least, but it cannot live migrate.
Traffic labels:
Management: cloudbr1
Guest: cloudbr0
Public: cloudbr0
Thanks for the guidance Gabriel, it is much appreciated.
Thanks, Jim
Hi,
We were try to deploy io_uring, but is supported since kernel 5.1 and
CentOS 8 has Kernel 4.8.
There is a backport request at redhat but is still in progress since april.
https://access.redhat.com/solutions/4723221
I tnink redhat will include this when the updates the kernel version.

Hi Wei,
I modified the qemu file on both hosts (and restarted the services just to be
on the safe side), but am still running into the same error.

Hi Wei,
Hmm... that's a little frustrating, since not all of the hardware I'm working
with is all the same.
Sure. Here's the github link: https://github.com/apache/cloudstack/issues/5717

Wei,
Yes, both hosts have /etc/libvirt/hooks/qemu and python3 installed.
In this case, they both have the same names for their interfaces (enp3s0f0 and
enp3s0f1), but host 1 is using enp3s0f0 and host 2 is using enp3s0f1.
