KVM and .18 kernel

[SamTzu]

I was moving KVM VM's to a new Proxmox and run in to a snag.
Proxmox 1.5 could not get the command below to work.
I browsed around the net and realised it's the lack of KVM SCSI support in .18 kernel.
All I had to do to get the VM to start was to replace if=scsi to if=ide and voila.
Manually copy pasting the edited command on the host started the VM.

/usr/bin/kvm -monitor unix:/var/run/qemu-server/119.mon,server,nowait -vnc unix:/var/run/qemu-server/119.vnc,password -pidfile /var/run/qemu-server/119.pid -daemonize -usbdevice tablet -name server.internet-content.net -smp 2 -vga cirrus -tdf -k fi -drive file=,if=ide,index=2,media=cdrom -drive file=/var/lib/vz/images/119/vm-119-disk.qcow2,if=scsi,index=0,boot=on -m 512 -net tap,vlan=1,ifname=vmtab119i1,script=/var/lib/qemu-server/bridge-vlan -net nic,vlan=1,model=rtl8139,macaddr=A2:2A:34:96:93:B0 -id 119 -cpuunits 1000

Plaah...
Just noticed that Proxmox VE 1.5 - New Kernel 2.6.24 that supports OpenVZ is just out.
All I had to do was upgrade to .24 kernel to fix the problem.
Well, live and learn.

fyi, Proxmox Kernel 2.6.24 support OpenVZ since the first beta release, V 0.9.

 

[SamTzu]

Yup, but I'd rather not use Betas on live servers.
For testing it fine and if the 'stable' version has a bug that must be solved quickly.

New to Proxmox & just setting up a few servers I normally run with vmware server. Should I install the 2.6.24 kernel ? is it regarded as stable with Proxmox ?
or stick with the ProxmoxVE 1.5 standard install kernel 2.6.18 ?
I intend to use both OpenVZ & KVM

Thanks
Garry

PS The other day in the office I needed a running winxp, so as easy as 1 2 3 Proxmox KVM & installed winxppro via .iso and done! I'm sure it leaves vmware server for dead

2.6.18 contains the stable OpenVZ. 2.6.24 contains the newest KVM (and a quite usable OpenVZ)

So it just depends what you need, if you are happy with your 2.6.18, keep it.

Thanks for the reply Tom,
hmm 'a quite usable OpenVZ' so not as usable as .18 ?

the 2.6.18 (RHEL5) OpenVZ kernel is the only stable and feature complete branch.

see http://wiki.openvz.org/Download/kernel

this does not mean that the others are not usable, but they are not marked as "stable" from the OpenVZ developers.
