Update: I found this link:
http://wiki.openvz.org/Resource_shortage
--Issued (guest) ' cat /proc/user_beancounters ' and noticed 13 failures for shmpages:
shmpages 8192 8192 8192 8192 13
--Issued (host) ' vzctl set 101 --shmpages $((8192*8)):$((8192*8)) --save '
Guest:
Knoppix:/proc# cat user_beancounters
Version: 2.5

--Reran apt-get install and it went OK.
--Still dunno how to check disk-space from within guest tho, or why this resource mattered??

Host: Dual-core Pentium-D @ 2660MHz with 2048MB RAM
--Using the latest OpenVZ/Knoppix Live-cd from lwn.net link
( http://lwn.net/Articles/234354/ )
( I have fairly extensive experience with vmware WS / server, but none so far with openvz except for what's on the CD and wiki )
Host:
1 vzctl create 101 --ostemplate debian-3.1-i386-minimal
2 vzctl start 101
3 vzctl exec 101 'ps ax'
4 echo 1 > /proc/sys/net/ipv4/ip_forward
5 ifconfig
6 ifconfig -a
7 ifconfig venet0 up
8 ifconfig
9 vzctl set 101 --ipadd 192.168.2.227 --save
10 ping 192.168.2.227
In guest, I set up access to my local Squid proxy:
11 ping 192.168.2.250
12 export http_proxy=http://192.168.2.250:3128
13 export ftp_proxy=http://192.168.2.250:3128
14 apt-get update # Works OK
15 apt-get install joe mc screen

--How do you tell how much disk space the guest has, from in-guest? Any advice? TIA
--BTW, I couldn't get networking in-guest when the openvz CD was booted from within vmware ws 5.5.4. This was all done after rebooting the livecd natively, on the bare HW.

Hello, you wrote:
Quote: | Hope this gets updated in the doc for the next Livecd rev; it would be a good idea to update it on the Web for the livecd in the meantime.
| Ahem... I thought this fact is mentioned in docs: http://wiki.openvz.org/Download_live_CD#Limitations
But you're right it isn't mentioned on the page, that appears after CD boot. Well, can you please add this information to http://wiki.openvz.org/Basic_operations_in_OpenVZ?
Thanks in advance!

You can use this article: http://wiki.openvz.org/Creating_OpenVZ_LiveCD. You don't need to repeat all actions, if you have OpenVZ livecd. Only extract KNOPPIX compressed image that is on CD, chroot to it and increase shmpages default limit (it's located somethere in vzctl files).
As concerns DHCP. You should use veth instead venet device in VE and then everything is as usual: dhcp-client in VE.
If you will have additional questions, please post them as separate threads, because initial problem is cleared.
Thank you,
Vasily.
