Hi *,
ssh login attepts from my host system to to a centos-5 64 Bit container suddenly take up to 30 secs before the password prompt appears - as to one or two secs before.
Between the short login response time and the long one I worked on kernel parameters on host and vm (shm) to accomodate an Oracle-11 installation, but I can't get back to the "original" state.
I even created an new centos-5 container from a template to test the login response time - same effect: acround 30 secs.
Looks like I messed up something on the host.
Any ideas?
Joachim

I changed some kernel parameters of the VM host.
After a "sysctl -p" they showed up OK on the VM host.
From then on the ssh login to a VM took "long" - till I rebooted the vm host.
