...able to use 4GB. My system on boot recognize 4GB ram but allocate only 2GB. Extract from dmesg: Warning only 4GB will be used. Use a PAE enabled kernel. 3200MB HIGHMEM available. 896MB LOWMEM available. Memory: 2056396k/4194304k available (2043k kernel code, 39416k reserved, 846k data, 232k init, 1179584k highmem) Why it suggest me to "Use a PAE enabled kernel."? Thanks. Giuliano.

I ran some iperf tests today and it looks like the etherbridge is the limiting factor on throughput. In the beforetime, I saw great throughput to the VMs; over 800 Mbps. With the bridge, the numbers are in the 400s somewhere. Is this the speed I can expect from the bridge? Is there some tuning I should try, or another way to get more bandwidth into the VMs? This is with xen-2.0, 2.4.27-xen0
