My system is Gentoo amd64, with latest update. I emerged the latest openvz, and want to start a Ubuntu VPS on my system. I am using the 'basic' configuration file, and the quota options are set as default, as follow:
DISKSPACE="1048576:1153024"
DISKINODES="200000:220000"
QUOTATIME="0"
If I try to create a CT, I will get the following error message.
Creating container private area (ubuntu-10.04-x86_64)
/usr/lib64/vzctl/scripts/vps-create: line 31: 13037 Killed
tar -C "$VE_PRVT" ${TAR_OPT} ${OPT} -xf "$PRIVATE_TEMPLATE"
vps-create ERROR: Error in tar --numeric-owner -z -xf /vz/template/cache/ubuntu-10.04-x86_64.tar.gz
Received signal: 9 in /usr/sbin/vzquota
Killed
the system may appear to be alive, but as soon as there is any IO action, like open a file with vim, the system hangs.
i am really new to openvz, and have no idea where should i start to troubleshoot this problem.
below is the dmesg output: (the system hangs after that message, so i am not sure if it is the complete output)
