blktap module needed for kernel 4.16. kernel 4.16 needed for latest Ceph with bluestore backend.
We want to make this CI stuff, that we will be the goal of Sam, our new recruit coming in 20 days!
edit: @r1 you are obviously more than welcome aboard to help us on that!
@olivierlambert Would you want to include this in that CI? May be on an experimental branch.
I don't know yet, it's likely we'll have multiple CI, one for "stable", one for "experimental" with a lot of fun stuff inside
I'll get the patch added to GitHub for open access till then.
I added the patch on Github - I'm testing it in various systems.
If you are using RBDSR then use the extra flag
device-config:rbd-mode=kernelwhile creating the PBD.
Is there a way to get this upstream?
I don't know yet.
I will try for centos-release-xen as its a SIG and maintains Xen specific dom0 kernel.
The CentOS packaging of Xen is very different from XenServer/XCP-ng. "Upstream" for me meant XenServer, no CentOS (at least for a bit)
@r1 Sorry Rushy,
Why did you create a patch instead of directly sent a pull request to the original blktap2 driver.
I'll say it's time to stop to make unofficial patches which can be overwritten by upstream updates.
Let's change the upstream directly.
@maxcuttins There are two packages. User level blktap driver that you referred
blktapand a builtin kernel driver
blktap2. Said patch is against mainline kernel as additional driver.
You still need to have user land blktap from https://github.com/xapi-project/blktap
There are instructions lying around https://xcp-ng.org/forum/topic/122/how-to-build-blktap-from-sources/ to build user land blktap (its without patch).
