Subject Re: CS 4.2 KVM - unable to give instances more than 3GB or RAM
Date Thu, 06 Feb 2014 16:11:50 GMT
Hi Marty,

I am running CentOS 6.5 64bit host with CloudStack 4.2.0, I am having a lot
of issues. I can't install FreeBSD 10 64bit only FreeBSD 9.2 i386.

can't allocate more than 3GB of RAM on guest instances, running 64bit
Centos on guest.

any recommendations?
