[Xen-users] Short how to for RHEL5 as dom0 and RHEL5 as domU
I was looking for step by step installation for RHEL5 as dom0 and RHEL5 as
domU, but could not find it.I put some instructions, hope it will save some
time for somebody. If you will find some errors please fix them :)
I assume that you already have rhel 5 up and running (webserver as well).I will
install guest system in paravirtualized mode (mine processor does not support
I.Xen DomU installation
1.Install xen kernel
2.When i tried to install xen : rpm -Uvh xen-3.0.3-25.el5.i386.rpm -Disk5
I had following dep missing
error: Failed dependencies:
bridge-utils is needed by xen-3.0.3-25.el5.i386
libSDL-1.2.so.0 is needed by xen-3.0.3-25.el5.i386
libblktap.so.3.0 is needed by xen-3.0.3-25.el5.i386
libxenctrl.so.3.0 is needed by xen-3.0.3-25.el5.i386
libxenguest.so.3.0 is needed by xen-3.0.3-25.el5.i386
libxenstore.so.3.0 is needed by xen-3.0.3-25.el5.i386
python-virtinst is needed by xen-3.0.3-25.el5.i386
xen-libs = 3.0.3-25.el5 is needed by xen-3.0.3-25.el5.i386
rpm -Uvh bridge-utils-1.1-2.i386.rpm -- Disk2/Server
rpm -Uvh SDL-1.2.10-8.el5.i386.rpm -- Disk2/Server
rpm -Uvh xen-libs-3.0.3-25.el5.i386.rpm -- Disk3/Server
rpm -Uvh --nodeps libvirt-0.1.8-15.el5.i386.rpm --Disk5/VT, i had to do it with
nodeps, not sure if it's right but works for me.
rpm -Uvh libvirt-python-0.1.8-15.el5.i386.rpm -- Disk5/VT
rpm -Uvh python-virtinst-0.99.0-2.el5.noarch.rpm -- Disk5/VT
rpm -Uvh xen-3.0.3-25.el5.i386.rpm -- Disk5/VT
should be all set :), now you have to edit this :
default=0 <--- change this from 1 to 0 if you want that xen kernel would start
title Red Hat Enterprise Linux Server (2.6.18-8.el5xen)
module /vmlinuz-2.6.18-8.el5xen ro root=/dev/VolGroup00/root rhgb quiet
title Red Hat Enterprise Linux Server (2.6.18-8.el5)
kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/root rhgb quiet
save it and reboot it. On the boot you will get that it cannot load some kind
of module (microcode i think). You can ignore it, because it's compailed in
kernel. After reboot, if you do uname -r you should get this : 2.6.18-8.el5xen.
issue : xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 1894 2 r----- 27.4
should give you similar output. If not check if xend is running.
3. Virtual manager installation:
rpm -Uvh gnome-python2-gnomekeyring.... - DIsk5/Server
rpm -Uvh virt-manager....- DIsk5/VT
II. Rhel5 as DomU installation:
1.I got this from this forum from some smart guy :). You will need to have iso
images for all 5 RHEL5 cd's.
Find a partition where you have around 3G of space.
create directoies CD1 CD2 CD3 CD4 and CD5.
Copy rhel-5-server-i386-disc1.iso to CD1 ...disk2->CD2 and so on.
now we have to export these directories through webserver. To do this we need
to loop mount them on webserver tree. Create same 5 dirs under /var/www/html/
and loop mount them.
mount -o loop /root/CD1/rhel-5-server-i386-disc1.iso /var/www/html/CD1
mount -o loop /root/CD5/rhel-5-server-i386-disc5.iso /var/www/html/CD5
if you would go to /var/www/html/CD1 you should see content of disk1
you should be able to see them like this as well:
http://yourip/CD1 (if you do it though ssh make sure ip tables allows http
Launch virtual machine manager, when you reach install media URL:
enter http://192.x.x.x/CD1 --- it wont work with localhost or 127.0.0.1 address.
follow other steps in wizard and you should be all set !.
