Virtfs copies the ftp files (see above under The FTP files) only if you activate FTP service for the service.
After the files are copied over you will have to edit them if you want your virtual server's ftp server to act differently than the main servers.
Some applications require libraries to be pre-loaded. I suggest you chroot to the
server (through Virtfs) as root and run ldconfig. You may have to edit
/etc/ld.so.conf within the virtual server to specify which directories are
to be included. Again, the contents of /etc/ld.so.conf can be altered everytime a server is created within
/etc/virt.conf.
As each Linux flavour required their own log directory, I suggest after creating a
virtual server, you compare the log directories. For example, Virtfs will not create
/var/log/httpd as Redhat Apache RPMs do. You should create the directory.
Virtfs does create the standard Sendmail directories for you (this is in the
<Shell Commands> section of /etc/virt.conf).
