Samba-Server Question

[djonny]

Hello all,

First sorry, for my bad english

I'm new on the sector virtualization.

I've install ProxMox on my Server and I have 3 VM's 1 OpenVZ and 2 KVM

My Problem is that I use one of the KVM as a Fileserver VM with Samba Server.
The Problem is that I get on a Gbit Network only 10Mb/s to read and the really crazy thing 25Mb/s to write?

normally read is faster than write. Without Proxmox I have a transferrate of 70Mb/s read and 40 Mb/s write

Is there any difference in Speed if I use OpenVZ or KVM?
Or is this a bad Samba Konfiguration?

I hope you understand what I mean, if you need more details please ask me.

edit: The Fileserver System is Ubuntu 10.04.1
and ethtool shows me that eth0 is only with 100mbit

do you use virtio network card and virtio disk emulation for this KVM guest?

virtualizing file servers are not the best idea if you want full performance. think of installing samba on the Proxmox VE host.

I hope you understand what I mean, if you need more details please ask me.

thanks for the quick answer

I need vmbr0 Network card, the Hard Disk is added via qm set <vmid> -ide# /dev/sdb
and then mounted in ubuntu

I need this KVM for Fileserver and OpenVPN.
Can I install this 2 services on the Host System?

And can I mount the Hard Disk (This is a Raid 5 Array on a Raid-Controller) on more than one vm?

I need vmbr0 Network card,

I am talking about the emulated nic, not the host network. see http://pve.proxmox.com/wiki/Hardware_setup_for_KVM_guests_(Video)

the Hard Disk is added via qm set <vmid> -ide# /dev/sdb
and then mounted in ubuntu

you added it as ide, try virtio.

yes.

tia djonny

not really a recommend solutions, what do you want to achieve?

 

[djonny]

the emulated nic is a rtl8139
how I can delete this as ide? that I can add the device as virtio?

[tom]

watch the video!

for the nic, take virtio instead of rtl

for the disk, just edit the config file /etc/qemu-server/VMID.conf
and replace 'ideX:' with 'virtio0:'

I would definitely try running the samba server in OpenVZ. That should give you nearly host speed. I've been using it for almost a year - so far without problems.

Thanks for all the great answers

now I have Install Samba on the Host System and I have a good performance, a litte bit crazy but better than before, 60Mb/s read and 80Mb/s write (confusing)

later I will try if there is a difference between virtio and ide

thanks to all!!
