Hello forum,

I'm working for a company that uses VMWare's products. I want to convince them to migrate and consolidate current servers in a HA configuration with Proxmox 4. We need HA, snapshots, and HW id preservation.
I like Proxmox very much, I think it's a fantastic product, easy to use but very powerful.

I built a test environment with 2 identical HP servers and a notebook just for quorum.
I configured glusterfs with a replicated setup, created empty VMs with qcow2 disks and cloned successfully 5 VMs with clonezilla.

However, I've 2 license servers that relying on the hw id. So, I've tuned the machines in /etc/pve/qemu-server, added disk serial but VM displays only 20 characters, instead of full length disk serial.
Googling around I discovered that is a Qemu-KVM blockdev driveinfo limit, and there's a patch to address this issue, but analyzing the source code of QEMU-KVM-2.5.1 it seems to me that the patch was already applied.

There are any options that I don't know to bypass 20 characters limit?

Thank you very much

Marco

Please open a bug report at bugzilla.proxmox.com with all information about the patch you found. I guess we can change the limit then.
