Hi !

We planned migration our production servers under Debian Etch/Vmware server 1.0.6 to proxmox ve.

I need some recomentations in order to do it with the easy way and the minimal problems in this process, assuring perfomance and reliability.

My questions is about:

a) Debian servers migration is better under OpenVZ ?
b) Sles 10 server is better under KVM ?

Any help are welcome, specially with SLES 10, because is working with Oracle Application Server 10g and give the principal services.

Thank in advanced.

Hi,
it's as allways - it's depends...
The easies way for migration is kvm - transfer the diskfiles (perhaps convert it), create new VM with this diskfiles, start VM (perhaps change fstab-entry), perhaps change udev-rule for Network - that's should be all.
with OpenVz you transfer single Services - like install MySql and Apache inside the VM and copy the data- and configuration files from the old server.
The benefit of this is the small footprint and the good speed - especially noticeable with a mysql-server which runs sometimes under heavy load.

But also the storage-modell can be the decisive factor - with kvm you can use shared storage, with openvz only local storage (except with bind-mounts).

Hi guys,

I just installed a fresh SLES 10 SP3 vm on kvm with the 2.6.32-2 kernel and everything except virtio-net work fine (vm: SCSI-Storage, E1000-Network). If someone knows how to aktivate virtio-network (via Suse KMP) please help.
