Hello, trying to replicate a rh el 6.1 configuration to a CentOS 6.0+CR. Original upstream server was installed in 6.0 and then updated gradually up to 6.1 and other packages (up to about first days of October). It is registered to additional channels such as High Availability, Resilient Storage. Overall its situation is this: # rhn-channel -l rhel-x86_64-server-6 rhel-x86_64-server-ha-6 rhel-x86_64-server-optional-6 rhel-x86_64-server-rs-6 rhel-x86_64-server-supplementary-6 rhel-x86_64-server-v2vwin-6 rhn-tools-rhel-x86_64-server-6 At the moment, I found some differences. I'm going to post different e-mails for different packages - flac On rh el 6.1 # rpm -q flac package flac is not installed On CentOS it is now installed, but if I try to remove it I get: [root at crhev3 ~]# yum remove flac Loaded plugins: downloadonly, fastestmirror, refresh-packagekit Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package flac.x86_64

Installed size: 129 M While on rh el 6.1 server I do have Virtualization packages.... # rpm -q virt-v2v virt-v2v-0.7.1-4.el6.x86_64 I see that in general some of my CentOS packages have newer versions, because my upstream is not fully updated at this moment But virt-v2v in CentOS is 0.7.1-3 vs 0.7.1-4 in RH EL I don't know if this could be the cause...
