Re: [Xen-devel] Payed Xen Admin

Usually, I've seen (null) domains are not running but their Qemu DMs are running. You could probably remove the (null) from the list by using "kill -9" on the qemu pids.

Good Morning,

 

we have some issues with our Xen Hosts. It seems it is a xen bug but we do not find the solution.

HVM VMs change sometimes in the state (null).

 

We still upgraded xen from 4.1.1 to 4.8, we upgraded the System Kernel –

 

root@v8:~# uname -a

Linux v8.ip-projects.de 4.8.10-xen #2 SMP Mon Nov 21 18:56:56 CET 2016 x86_64 GNU/Linux

 

But all these points dont help us to solve this issue.

 

Now we are searching a Xen administrator which can help us anylising and solving this issue. We would also pay for this Service.

 

Hardware Specs of the host:

 

2x Intel Xeon E5-2620v4
256 GB DDR4 ECC Reg RAM
6x 3 TB WD RE
2x 512 GB Kingston KC
2x 256 GB Kingston KC
2x 600 GB SAS
LSI MegaRAID 9361-8i
MegaRAID Kit LSICVM02

 

 

The cause behind this Setup:

 

6x 3 TB WD RE – RAID 10 – W/R IO Cache + CacheCade LSI – Data Storage

2x 512 GB Kingston KC400 SSDs – RAID 1 – SSD Cache for RAID 10 Array

2x 256 GB Kingston KC400 SSD – RAID 1 – SWAP Array for Para VMs

2x 600 GB SAS  - RAID 1 – Backup Array for faster Backup of the VMs to external Storage.

 

 

 

 

Mit freundlichen Grüßen
