I want to share the current state of oVirt on Fedora 28, hopefully it will
save time for other developers.
1. Why should I run oVirt on Fedora 28?
- Fedora is the the base for future CentOS. The bugs we find *today* on
Fedora 28
are the bugs that we will not have next year when we try oVirt on CentOS.
- I want to contribute to projects that require python 3. For example,
virt-v2v
require python 3.6 in upstream. If you want to contribute you need to test
it on Fedora 28.
- I need to develop with latest libvirt and qemu. One example is incremental
backup, you will need Fefora 28 to work on this.
- CentOS is old and boring, I want to play with the newest bugs :-)
2. How to install oVirt with Fedora 28 hosts
Warning: ugly hacks bellow!
- Install ovirt-release-master.rpm on all hosts
dnf install http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm
- Install or build engine on CentOS 7.5 (1804)[1]
- When provisioning a host, make sure you have lvm2-2.02.177-5.fc28
without it, no block storage you[2]
- When adding a host, disable "Configure host firewall" - it does not work
now
I hope that Sandro team will fix this issue soon.
- Adding a host will fail, because without firewall setup, port 54321 is
not reacable.
to fix this, configure the firewall manually, or disable it
iptables -F
This is pretty lame because you have to apply it again after restart, but
it was
good enough for now.
- Because the host was not reachable, we don't configure the host network
so the host will be non-operational.
To fix this, open host > network > setup networks and assign ovirtmgmt
to the host management nic. The host will become UP after that.
I hope that Dan team will fix it soon.
- Adding storage will fail because sanlock selinux issue[3]
To fix, set selinux to permissive mode:
setenforce 0
At this point you should have a working setup.
3. Building and instaling vdsm from source on Fedora 28
- Install build dependencies using
dnf install `cat automation/check-patch.packages.fc28`
- Clean the source (needed if you rerun ./autogen.sh with different options)
git clean -dxf
- Configure vdsm with hooks - for some reason 2 hooks are required
on Fedora but not on EL.
./autogen.sh --system --enable-hooks
- Build
make
make rpm
- Install the packages at /home/user/rpmbuild/RPMS/{noarch,x86_64}
- if vdsm was never installed, you need to configure and enable it
vdsm-tool configure --force
systemctl enable vdsmd
systemctl start vdsmd
At this point you can test the new bugs you added to vdsm :-)
[1] I did not try to install engine on Fedora 28. I guess engine folks can
share if there are issues with this.
[2] https://bugzilla.redhat.com/1575762
LVM team fixed the issue couple of hours after I asked about it in #lvm
We had a build for testing couple of days later.
[3] https://bugzilla.redhat.com/1593853
We are still waiting for selinux folks response.
Happy hacking!
