Lightbulb redhat virtualization question?


Hi All,

I would like to install 2.1 as guest os on Redhat 5.0? is there any possibility?

Redhat support two types of virtualization guests, as below.but it also says; it also support third party OS. so can i install rh2.1 as well? instead third party OS?


Types of virtualization:

Red Hat Enterprise Linux provides support for two types of virtualized guests, para-virtualized and fully virtualized.

Para-virtualized guests offer the highest performance and do not require special processor capabilities. Para-virtualization is available for Red Hat Enterprise Linux 4 (Update 5) and Red Hat Enterprise Linux 5 guests.

Full virtualization is available for a wider range of guests, including Red Hat Enterprise Linux 3, 4 and 5, and also for third party operating system guests. Full virtualization requires Intel VT or AMD-V processors.

my scenario.

HOST OS: redhat 5.0

Guest OS: RH2.1 & RH3.0

If anyone know, please let me know, your help will be more appropriated.


Thanks in Adv.

yes aboslutely possible, but if you have an Intel VT system (or amd equivalent) then you'll basically get better performance.

Much Thanks acid_kewpie,


I've IBM Xseries 3650 T(7979 AC1)how do i check if this server supports Intel VT system? is there anyway i can check from Linux?

Also, how to install Rh2.1 and 3.0 on redhat 5.0? I followed below link to intsall guest os.

while Creating a New Virtual Machine on RH 5.0 i've created file called redhat2 under /var/lib/xen folder.i got error while initialization the Disk(before disk durd screen). its giving me I/O error. I can not go further for installation. I dont know whats wrong with that.

https://www.redhat.com/docs/manuals/...ll-wizard.html


In addition i've select "Full virtualization" option to install rh2.1 and 3.0. I tired installing using CD's and ISO. but no luck...

Please advise..

i guess you'd corss reference your cpu(s) with intel.com or whatever, they'll want to be boasting about it if they do it. anything less than a year old should be doing it now.

cat /proc/cpuinfo

For Intel chips look for (I believe) vmx in the flags section of the output. If vmx is there, your'e golden, if not, you 'could' still get things to work in para-virtulization mode.

I am having trouble installing RH 2.1, I believe this "bug" will help Redhat engineer to make Rh 5.0 more stable. I've snapshot of that bug, can any one please tell me how to attach images with this reply?

Below are the steps I followed to install Rh2.1.

1) gave hostname

2) selected Full virtualization

3) assigned installation media (ISO disk1 image)

3) assigned storage space by selecting "Simple file" option.

File: /xen/redhat2 (also, setup SELinux policy using "restrecon -v /xen)
File Size: 6000MB

4) Allocated memoory and CPU

VM MAx Memory: 512
VM startup Momory: 512
VCPUs: 1

What kind of error do you get? Did you enable virtualization/VT-X support in the BIOS?

I want attached snapsort of error. can anyone please guide me?

I believe virtualization/VT-X support in the BIOS should enabled by default. I will double make sure this.

Thanks again
