CloudLinux 7, CloudLinux 6h, CentOS/RHEL 7 patches are ready/waiting for you in test channel.

* Note: If you are running Xen PV -- they will not work (see post below).

To deploy them:
edit /etc/sysconfig/kcare/kcare.conf
Add:
PREFIX=test

Run:
kcarectl --update

If you see any issues with the server -- contact our support. 

We really need your feedback. This patch is more complex than any we have ever done, and it is impossible to fully test it. If you have a large park of servers, consider having at least one of them tested with test channel, BEFORE we push it to production.

We have received one crash report, that is NMI crash. We will not be releasing patches today, as we have to fix this issue first.

Thank you, everyone, who helped us test this patch.

New patchset released to test for the same distributions as bellow with three more issues fixed. Hopefully, this will be the last 'test' patchset. Please, help us with testing it. It seems like we removed all issues that might cause the crash, and the two out of three issues were minor/didn't result in the crash.
 
OSes covered: CentOS/RHEL/CloudLinux 7, CloudLinux 6h as well as Proxmox 3.10 kernels.If you can test them -- we would greatly appreciate it. The issue found in the last round of tests has been fixed.

So far we had no negative reports and several positives. This is your last chance to test it before tomorrow's rollout of patches.
Please, try testing it on at least one machine.
