Re: [vserver] Virus scanning on a guest

Have straced the eset daemon on start and it appears to be failing here:

munmap(0xf750f000, 4096) = 0
open("/var/opt/eset/esets/lib/em001_32.dat", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
munmap(0xf74f6000, 102400) = 0
write(2, "error[38440000]: Cannot initiali"..., 69error[38440000]: Cannot initialize scanner: No such file or directory) = 69
write(2, "\n", 1

and the file does exist:

ls -l /var/opt/eset/esets/lib/em000_32.dat
-rw-r--r-- 1 root root 55888 Oct 2 15:52 /var/opt/eset/esets/lib/em000_32.dat

Any ideas please ?

First /tmp is not a file, it is a mount point (at least
on typical Unix/Linux distributions), and the question
here is how your /tmp is mounted (which might be too
restrictive, for security reasons, on this guest)

Those are definitely not required for a simple task like
virus scanning and I would strongly suggest not to give
that to a guest with a focus on security ...

First, check the mount options, then check with e.g.
strace -fF what the kaspersky tool is trying to do and
what actually fails.
