Infrastructure
I am setting up a testbed to investigate technical issues related to virtual machine management.
Hardware and Operating Systems
- 2 Dell 1950 machines, dual CPU, 4 cores per CPU
- One machine has a Centos-5 installation
- One machine has a Debian-squeeze installation
Software
- Centos-5 comes with Xen 3.0
- Debian-squeeze comes with Xen 3.3
- Debian-squeeze Xen packages have a problem with tap:aio.
Fix:<br\> ln -s /usr/lib/xen-3.2-1/bin/tapdisk /usr/sbin<br\> echo xenblktap >> /etc/modules
- Opennebula has been installed following this guide
- A few additional staps were needed:
- Install rubygems and rubygem-sqlite3
- A few additional staps were needed:
wget ftp://fr.rpmfind.net/linux/EPEL/5/x86_64/rubygem-sqlite3-ruby-1.2.4-1.el5.x86_64.rpm wget ftp://fr.rpmfind.net/linux/EPEL/5/x86_64/rubygems-1.3.1-1.el5.noarch.rpm sudo rpm -Uvh rubygems-1.3.1-1.el5.noarch.rpm rubygem-sqlite3-ruby-1.2.4-1.el5.x86_64.rpm
- Opennebula has to be added to the sudoers file for xm
- Sudoers should not require a tty
opennebula ALL = NOPASSWD: /usr/sbin/xm #Defaults requiretty
