Any original vserver have this bug.
I fix it in snapshot rh-vserver-1052304359.diff.gz (7 may).
For fix you must change one lines in kernel/sys.c.
From
asmlinkage long sys_sethostname(char *name, int len)
{
        int errno;
        char *nodename;

        if( (!capable(CAP_SYS_ADMIN)))
                return -EPERM;
To
asmlinkage long sys_sethostname(char *name, int len)
{
        int errno;
        char *nodename;

        if( (!capable(CAP_SYS_ADMIN)) && ! is_vps_admin())
                return -EPERM;

Also need fix sys_setdomainname.
