mmmhh... I'd use vmware or Proxmox.. in any case not as a xen host

Are you stuck with Debian?

[linuxhelp]

No, but its easier to setup some virtuall 32bit diffrent engines at 64bit engines..or not?

>> I LOVE SME SERVER <<!!!!

Moving this topic to the SME 7.x contribs forum, it is more appropriate there. Thanks!

[compdoc]

well, the problem with using a distro like Debian or Fedora, etc, is you have to set up everything by hand: the OS itself, networking and bridges, and VNC and other utils. And there are often speed bumps along the way - bugs, dependencies, etc etc.

Also, xen and qemu running on those distros has always been terribly slow in the past. I have always thought VMWare was terribly slow too...

I know all this because I have tried them all, and because Im struggling right now to get KVM running on Fedora 11, which has the newest version of KVM and the linux kernel .

Theres an easier way, if you want speed, ease of setup, and a rock-solid, enterprise class server that never goes down. It works fine with SME, and many other OSes I have running on it on several servers belonging to me and my customers. And it’s free.

Get XenServer from citrix. You download it, and install it, and administer it with an excellent Windows client called XenCenter.   www.citrix.com

I’ve been reading that even citrix will go with KVM someday, and I have had a Windows 2000 Server guest running in the newest KVM on Fedora 11, and I have to say, I think it’s finally running as fast as XenServer, but it’s a lot of work to get to that point...

Hello

thanks for reply, yes i agree, cause my feeling was too that my Phenom940-X4/4G-RAM Server was very slow
at access to bridget networking clients (tested-lenny-guests)

i will have a closer look at citrix-xen-based-on-centos.

Do anyone tested physical networking with xen? is the "IO-Performance" better?

i must solve my bottlenecks, at first remove the Cerc Raid-Card and switch to raid 0+1 of SME-mdraid.

In terms of native speeds for guests, I think the secret is the drivers for the paravirtual devices like the drive & network controllers within the guest.

Qemu/KVM on fedora can use the virtio drivers from redhat, so the quality and support is there. Xen has drivers out there if you search with google.
 
Citrix XenServer has excellent Windows drivers, but the installer for linux only recognizes a few major distros, and you often have to install them manually. Even then, it might not install.

Feedback:
New setup test with qemu works performant on a Phenom 1090T X6 / 8GB RAM @ 3200Mhz Engine / disabled Speedstep at Bios !! AMD-BUG!!
Base OS: Ubuntu 64 10.04
Virtualhost: Qemu
DomU: SME 7.5.1 on a second Hdd (no virtual hdd.img used as DomU Disc )!!! enabled 6 cores / 6GB RAM

runs better as vmware..

I haven't tried VM's on a AMD box.

We have a Intel Q6600 with 8G and 4 1TB drives in Raid 5 with esxi4 and it flies with both SME and MS server 2008 running on it.

I've downloaded citrix xen to try, but have never gotten around to putting it to the test..

I have no 64bit machine but on centos 5.5 32bit I installed 7.5.1 with that command:

Code: [Select]

virt-install -n sme751 -r 512 -f /home/vm/sme751.img -s 8 -l http://sme-mirror.firewall-services.com/releases/7.5.1/smeos/i386

virt-install -n sme751 -r 512 -f /home/vm/sme751.img -s 8 -l http://sme-mirror.firewall-services.com/releases/7.5.1/smeos/i386


Would that be a hvm or a pvm?

[fpausp]

Unfortunately on my server a pvm but on the amd64 it could be a hvm.

I do all my SME servers as full KVM inside http://pve.proxmox.com/wiki/Main_Page .. The new SME of virtualization!.
Its easy to add other LAMP Open Vz apps . Its stable and easy to try changes on SME (fire up another VM copy) Change hardware is
a simple install proxmox, Copy the VM lump of data, Add some Nic's, fire up , Have successfully converted SME\Vmware's and  Real windows servers- workstations
hard drives..using dd SSH.. in the Wiki..  Nic bonding works well.. Windows speed is Awesome all relative to Solid Raided hardrives. 
Will be extending our work setup to ProxMox Clustering, Using Affa to build the Virtual SME  etc. http://pve.proxmox.com/wiki/DRBD

After reading your post I tried proxmox and its realy cool, in the meantime I bought a 64bit machine (PRIMERGY TX100 S1 with xen 3330) but proxmox dont support raid. I am not sure at the moment what os I should take for the host. Should I use proxmox with tx100 raid1 or centos 5.5 with softraid1 and xen or maybe sme8 with xen. I think softwareraid is easier for recovery. What do you think ?
