Stefan,
I suggest you file a bug to http://bugzilla.openvz.org/

Hello,
Currently I have a Linux-VServer setup using the official Debian Etch
binaries with MySQL socket sharing similar to what is described in the
"Shared webhosting" article in the OpenVZ Wiki (it works the same with
Linux-VServer). Now that there probably will be official Debian Lenny
kernel images patched with OpenVZ support, I consider switching to
OpenVZ. The 2.6.26 images currently in Sid are very promising. But there
is a problem:
When I try to setup socket sharing as described in
http://wiki.openvz.org/Shared_webhosting#MySQL_socket_sharing (or just
starting my Linux-VServer virtual machines in OpenVZ) I cannot connect
to a socket listening in a different VE. Only when I connect from the
same VE the connection succeeds. I tried:
- hardlinking the socket
- bind mounting the containing directory
- directly connecting from/to VE0
I tried both MySQL and simply creating/connecting to the socket using
Netcat (the OpenBSD version works with Unix Domain Sockets). Related
strace output:
[...]
socket(PF_FILE, SOCK_STREAM, 0) = 3
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
connect(3, {sa_family=AF_FILE, path="testdir/testsocket"...}, 20)
= -1 ECONNREFUSED (Connection refused)
close(3) = 0
[...]
Using linux-image-2.6.24-openvz-24-004.1d1-686_004.1d1_i386.deb from
download.openvz.org doesn't change anything, but when using the stable
linux-image-2.6.18-openvz-18-53.5d1-k7_028.53.5d1_i386.deb, I can
connect without problems.
Am I missing something? Is the devel OpenVZ broken, or is it supposed to
be a feature and the stable version behavior is deprecated? Is it
configurable or is there a workaround? If the devel version's behavior
is correct, then the Wiki article should probably be changed to mention
that (and I would be forced to postpone my migration to OpenVZ). On the
article's discussion page there is a user who also failed getting this
to work.
Greetings,
Stefan Siegel
