I am also on gentoo. I can say that gcc does fail on VEs unless you
have high limits.  As a result I limit the building inside the VE and
make sure the -j param is also low. Note that the default limits are
ridiculously low for any system I have ever ran.

I would add more ram if it's only 2GB you can. 4GB of DDR2 memory is
$50 US right now. Generally my gentoo HN are 4 or 8GB desktop machines
running x86_64.


In the last month I have switched over to pregenerating my VEs using metro.

See www.funtoo.org.

I have modified the metro code (look at the drescherjm fork of metro)
a little to generate VEs for DNS servers and mail servers and I plan
to add samba PDCs as well so that in 5 minutes after some failure I
can add a brand new VE to my network to replace either a hardware
server or an other virtual server. And I actually needed that last
week to replace both dns servers and a mail server because of a
software failure in a gentoo xen box.
