If you install from rhn.redhat.com activate this channels (if x86_64)
for your system:
rhel-x86_64-server-5
rhel-x86_64-server-vt-5-beta
rhel-x86_64-server-5-beta
Then update your system to 5.4 and reboot to the new kernel
After that install this rpm's from rhel5.4 (dependencies will install
more packages):
kvm
virt-viewer
virt-manager
python-virtinst
libvirt-python
libvirt
kvm-qemu-img
bridge-utils
I have active VT Support in the system bios (vmx flag in /proc/
cpuinfo) on my intel i7.

Starting install...
Creating storage file... | 10 GB 00:00
Creating domain... | 0 B 00:00
and then you get the virt-viewer console for start install your guest.
There are more option for using kickstart files.
If you are using ssh to access you hypervisor use "ssh -X" for x11
forwarding virt-viewer.
Or you can install guests with virt-manager complete over the UI.
Define virtual networks and storage by Edit->Host Details.
After that create a guest with "new"....
With "virsh help" there are many commands available for vm management.
For example:
virsh list -> list you guests
virsh dumpxml testnode -> dump a xml from your testnode
virsh autostart testnode -> autostart your guest at boot up.
Here one xml from a running guest:
virsh # dumpxml testnode
<domain type='kvm' id='8'>
<name>testnode</name>
<uuid>0a5e51a8-2eeb-283d-ca99-83b6e92cdfd1</uuid>

<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='5907' autoport='yes' keymap='en-us'/>
<sound model='es1370'/>
</devices>
</domain>
With "virt-viewer testnode" you can access allways to your guests
console.
Hope this help you a little for starting and learning about this great
technologie!

One question, which exactly package did you install to use KVM ? I´m
going
to look for it in RHEL 5.4

Yes, it's not supported in RHEL5.3 by default, so I upgrade my
kernel to
2.6.24 and enable KVM , download KVM package and install it. Then I
can
use qemu command to create a VM.
I haven't tested RHEL5.4, you can try if there's such qemu command.

Re: kvm virtualization in RHEL 5.4 Beta, howto
2009/8/12 Le Wen <wenle@xxxxxxxxxx>
Hi there,
I don't know what to do in RHEL5.4, but in RHEL5.3, using
qemu-img create -f qcow /vm/vdisk.img 20G
to create the virtual disk
qemu-kvm -hda /vm/vdisk.img -cdrom /vm/iso/w2k3.iso -boot d -m
1024
to create the virtual machine,
and finally, using
qemu-kvm /vm/vdisk.img -m 1024
to boot the installed vm.
Hi Len,
I´m totally overwhelmed with your answer.
The use of kvm is one of the great, great news in RHEL, in fact, it´s
still
in Beta. So I don´t understad how you can use it on 5.3.
on the other hand I don´t have the qemu-kvm command in my RHEL 5.3
systems.
(the qemu commands comes with the supplementary packages but I don
´t have
the kvm command)
How do I install the qemu-kvm command?
Thanks for your answer,
ESG

Re: kvm virtualization in RHEL 5.4 Beta, howto
Hi Thomas,
thanks for your answer.
When I run virt-manager (as I do with xen) and try to use kvm I
dont see
this option anywhere.
When I try to add a connection the hypervisors avaliable are xen and
qemu
(like with previous version of RH)
How I build the kvm guest (sorry if this is a silly question, but I
don´t
see how to make it)
Thanks,
ESG

Hi all,
I have installed the RHEL 5.4 Beta (see the press
http://press.redhat.com/2009/07/02/red-hat-enterprise-linux-5-4-beta-now-available/?sc_cid=70160000000Hv6dAAC
)
and I want to test KVM virtualization, but I don´t know how to
test
because
I´m totall newbie to this kind of virtualization.
I have installed the KVM group from pirut, but I dont see how to
test
it.
someone knows a good KVM-howto and the utilities that comes with
RHEL
5.4
Beta for manage it?
You can use virt-manager, virsh, virt-viewer from rhel5.4 beta to
build
kvm
guests.
