10:30<AntiInit>help
10:31<AntiInit>need to get teh fekin thing workin
10:34<AntiInit>the answer may not be amd64 bit support is limited.

11:07<AntiInit>i dont know enough to even begin to understand where the problem may be, but given my recent experiences with amd64, my finger is firmly pointed in that direction.

12:08<kokoko1>caker, around?
12:12<kokoko1>How much RAM should we leave for host, atm we are running 7 UML on host a host with 2G RAM. UMLs got 1536M of RAM, which left 512M for the host. However atm we are in a sitution where we want to increase one of our UML ram which is going lot of swapping due running apache + mysql.
12:13<kokoko1>Due you thinks we can get 128M from host without effective host?
12:17<kokoko1>s/due/Do :)
12:50<AntiInit>is it possible to remove 64 bit support from the host kernel?
12:51<caker>kokoko1: yes, I do. The host needs very little. How much it has in swap is a good indicator
12:52<caker>kokoko1: also, echo 10 > /proc/sys/vm/swappiness
12:52<kokoko1>caker, thanks :)
12:52<caker>^-- will help keep the host from paging out
12:53<kokoko1>caker, swappiness is 60 atm
12:54<caker>yeah, that's the default
12:56<kokoko1>caker, you want me to set swappiness on host right?
12:56<caker>Yes
12:56<kokoko1>caker, what about setting swappiness inside UML gives any benefit?
12:57<kokoko1>Just curious :)
12:57<caker>that's up to you. It's a trade off between a smaller cache requiring more disk hits because less is swapped
12:57<caker>or the other way around
