@stormi plus this update?

That kernel update is already available on 8.1 indeed, through yum update.

Did anyone try VM export/import to see how much the performance has been improved?
More interesting would be if someone tried it with 10G or making backups with XOA.

Not yet but I'd be really grateful to anyone who could benchmark this!

So, the main remaining development before RC is an updated installer to allow it to boot the alternate kernel in cases where the main kernel has issues. And also an option to boot with only 2G of RAM to workaround Ryzen APU "black screen" issues.

last week I installed a new server XCP-ng 8.1. But the filesystem is still Ext3. (by the way XO connects without problem but you need XCP-ng Center Development build to access)
Today I will install a new server, what should I do to get ext4 in the filesystem?
Thanks

What do you mean? SR file system or root filesystem?

I don't think you should trust XCP-ng Center on this. What do you think @borzel?

Check the output of mount instead.

onur

here is the output. So I assume ext4 should be default when selecting EXT on the setup.

It's ok, the SR is mounted as ext4 so this means it was created as ext4.

great thank you very much @stormi . As you suspected, XCP-ng Center shows wrong format (I guess here is a bug for XCP-ng center devs)

type ( RO): ext

As expected. The ext type has no information of the FS version in its name.

already created bug for XCP-ng center, but it looks like system is not reporting ext type

olivierlambert

Yes, it was just to be sure it's a XCP-ng Center issue Now we are 100% sure.

I think we should not trust I assume the ext4 uses internally the same xapi-ID like the old ext.

stormi

A better label would just be "ext" so that it works both for ext3 and ext4.

Running two hosts on the beta in my lab and so far have had no issues at all (touch wood). Looking forward to this hitting production.
