hi all iam new to linux this is my very first post .hope some body can help me sorry if the my question is too basic
i am trying to install the rhel 6 using virtual machine(virtual box ) and iam getting the error as
"Unable to read package metadata. This may be due to a missing repodata
directory. Please ensure that your install tree has been correctly
generated.

Cannot retrieve repository metadata (repomd.xml) for repository:naconda-base-201009221732.i386."
i would also like to know what is the reason for this error , i try to goggle it and seems most ppl are facing the same issue and they are directing to some mailing list like rhn-satellite can some somebody can explain what is that mail listing and how we can use the mail listing to dig information .Tnx in advance

seeing as RHEL 6 is NOT FREE
have you asked the people over at Red Hat .
You DID buy a license for rhel6 ? right ? Then use your paid for support .

IF you do NOT intend to pay for rhel that do not use it !
Instead instal CentOS 5.5 ( centOS 6 ? should? be out sometime in the next ~3 months)
it is the FREE community supported version of RHEL
