nTh among all

Should be simple, the number of times I’ve done it, but I’ve ended up searching google for how to do so. Again. vim /etc/sysconfig/network, add “HOSTNAME=newhost” or change it. Also, vi /etc/sysconfig/network-scripts/ifcfg-eth0, add “DHCP_HOSTNAME=newhost” for the hostname to be sent with DHCP requests. Have to find out if setting up the hostname with the kickstart […]

Disable the hardware clock The Xen domU will use the host’s clock, so we replace hwclock with an empty shell script echo exit 0 > /sbin/hwclock (from blog.jphoude.qc.ca/2007/10/26/centos-5-xen-images-part-1/)

Has been nothing but a pain. Seriously. Tried justindthomas.wordpress.com/2009/04/03/installing-nexentacp-2-rc1-on-xenserver-5/ . Close, but no cigar. Installing goes fine, but switching from HVM to PV kills it. bderzhavets.wordpress.com/2009/03/20/pygrub-install-opensolaris-200811-at-xen-unstable-dom0-with-2629-rc7-pvops-enabled-kernel/ looks good, but I have no idea where he’s getting the kernel and ramdisk from. I’ll be trying wiki.tardis.ed.ac.uk/index.php/OpenSolaris_Xen_domU, blogs.sun.com/levon/entry/opensolaris_2008_11_guest_domain and blogs.sun.com/levon/entry/opensolaris_2009_06_guest_domain over the weekend from a clean slate, […]

Using the Nexenta 3 release to get a better userland system than opensolaris. It’s based off OpenSolaris build 134, and still comes with ZFS, so it fits my needs perfectly. Since some customization has to be done first, it has to be installed in HVM mode. Which… has a few gotchas. 1. Only 4 devices […]

Have decided to go with Fedora 13 for my Xen install. Reaons being: VMWare and XenServer don’t support USB Passthrough, which I want to run one of the VMs as a home server, and will pass 2 printers through to it. CentOS is running off an old kernel and Xen version. If I want the […]

In Fedora 13 (and likely others), use cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime && ntpd -q, where $timezone is your timezone. (The ntpd -q is likely unnecessary, but, eh. It’ll force an update to the system time.)

Trying a new VM host that uses an ASUS motherboard. Unfortunately, old version of kernel in CentOS 5.5 means that no networking ever comes up. Specifically, the Atheros L1 Gigabit Ethernet driver isn’t in such an old version of the kernel. (Only came in in 2.6.21, centOS 5.5 is 2.6.18) Fix: Going by the page […]

Problem: Apache’s default SSL configuration doesn’t work. “\x16\x03\x01” 501 shows up in /var/apache2/2.2/logs/access_log Situation: The default config doesn’t have Apache responding to an SSL query – instead, it sends an unencrypted response back, leading to the web browser showing an error page. Fix: Change the line in /etc/apache2/2.2/sample-conf.d/ssl.conf that has to Problem: Some php programs […]

Assuming cd image is in the working directory, qemu -hda /dev/domUs/centos5 -hdb /dev/domUs/centos5swap -cdrom ./CentOS-5.4-i386-bin-DVD.iso -boot d -vnc 0.0.0.0:0 Use a VNC client (ie. RealVNC) and connect to the display – [Hostname or IP Address of the Xen server]:0 Seems to be bloody slow, but working. For some reason, restarting it after the install causes […]

I’m hoping to essentially follow this: bderzhavets.wordpress.com/2009/05/02/debootstrap-ubuntu-jaunty-pv-domu-at-xen-331-f10-dom0-kernel-2630-rc3-tip/ Essentially, create LVs and format them (look at the previous posts for the how to), and have debootstrap installed on the CentOS host. Mount the LV in which you’re going to install Debian on by running mount <LV location> <mount location>. I did mount /dev/mapper/debian /mnt/debian. The command […]
