Hi,

I would like to upgrade RHEL 5.4 to 5.8 VM without subscription and a yum repository.

What other options do I have?

It may not be impossible, but it would be illegal and risky.

In short, don't do it.  You can not get the necessary packages right from Red Hat therefor you can never be sure they were not tampered with.

Do you have access to download the RHEL isos? You can mount the iso and do a yum update against the iso.

Depending on which tools you have/need? Is migrating to centos might be an option/consideration?
In the absence of a subscription, as suggested earlier, using an ISO you can update? Using the cdrom/ISO as the source (mount ISO to appear as a local "partition/folder"

Sounds good, any instructions on how to do this.  Mount iso and run the yum.

I do not believe so, the redhat updates/upgrades usually maintain major, minor,micro version and only modify the other version.

Do you have access to a redhat 5.8 install disks?

Without subscription and without the requisite media, the only way to get the newer kernel is to build it yourself.

Yes I do have the 5.8 iso, I am quite to new to Linux.

The whole point of me updating to 5.8 was to get the 2.6.24, the first time that I mounted an encrypted volume, it gave the following error message:

Your system uses an old version of the Linux kernel.

Due to a bug in the Linux kernel, your system may stop responding when
writing data to a TrueCrypt volume. This problem can be solved by upgrading
the kernel to version 2.6.24

you have to mount the 5.8 ISO or burn the iso and insert into the system.
you would then configure yum with the cdrom as a repo
then you can configure the updater to use the cdrom for the update rather than going out to search.

cd /mnt/redhat5.8
yum localupdate
