I am currently considering what to do regarding a Zope server that I have converted to Xen. To best manage the servers I want to split the Zope instances into different DomU’s based on organisational boundaries. One reason for doing this is so that each sys-admin will only be granted access to the Zope instance […]

I have just converted a Fedora Core 5 server to a CentOS 5 Xen Dom0 with Fedora Core 5 as a DomU. The process took a little longer than expected because I didn’t have console or network access to the DomU initially. It turned out that /etc/modprobe.conf was configured to have the tg3 device for […] I’ve been having problems with one of my Xen virtual servers crashing with kernel error messages regarding OOM conditions. One thing I had been meaning to do is to determine how to make a core dump of a Xen domain and then get data such as the process list from it. But tonight I ended […] I just needed to test something so I mounted the filesystem of one of my Xen domains in the Dom0 and chroot’d into it (I didn’t need the overhead of running a DomU for a quick test). Then strangely I found that my chroot environment had no apt-get and no dpkg installed. After a small […] A couple of days ago the hardware that is used to host this blog was upgraded – doubling the amount of RAM in the machine. To do this the machine was halted, memtest86+ was run to ensure that the new RAM worked correctly, and then it was booted up again. During that process my ssh […] I have recently been using virt-install on CentOS 5 to install some virtual machines (I previously posted a summary of the experience). One problem I had is the inability to do an install of Fedora to /dev/hda – it insisted on partitioning the disk and installing it on a partition. I have filed Red Hat […] I believe that an ideal installation process for Linux would have the option of performing a Xen install. The basic functionality of installing the Xen versions of the required packages (the kernel and libc), the Xen hypervisor, and the Xen tools is already done well in Fedora and it’s an option to install them in […] |
