If I disable openvz* repos yum works fine:
$ yum repolist --disablerepo=openvz-utils --disablerepo=openvz-kernel-rhel6
Loaded plugins: kernel-module
repo id repo name
status
sl-base SL 5 base
3,702
sl-security SL 5 security
updates 27
repolist: 3,729
10 hours ago the problem with openvz* repos was the same.
Any help on that?
