Migrating RH9 legacy system to VM
by Mark Rogers 03 Jan '08

03 Jan '08

I have an old (but still in use) RH9 system I want to migrate to a virtual machine. One of the main reasons for doing this will be performance: a database query on an internal website which is used regularly is taking 15s on the old hardware, where the same query on the same database on a virtual machine takes well under a second... The server is only used internally but all the same I want to minimise downtime. The "normal" method I'd use would be to shut down the hardware, take an image of the drive, restore it into a virtual machine, boot it, fix any problems (eg driver issues) as necessary. Depending how long that last step takes this could mean the system is offline for quite a while. I could create an empty VM, boot it to a live CD, and rsync the whole OS data from the old system to the new one, but I'm not sure which rsync options I'd need to use to make sure the user permissions copied across correctly (I assume that since /etc/passwd will be copied across it doesn't matter that the users don't exist initially), then make the VM's disk bootable, and take it from there; all of that I could do with the other system online and then fix the problems in the VM with the old system still online, ready to re-rsync later to catch up with any changes after shutting down all services like the database etc. But (a) I'm not sure how to make the VM boot and (b) I'm not sure what else would go wrong.

Hi Linux users I'm fairly new to Linux. Previously I have installed and used Ubuntu on my main P4 computer, dual booting it with XP Pro. That system became unbootable and I ended up reformating and re-installing XP Pro. I'm now looking at other distros to find better ones to use on an old Celeron 3 computer for surfing and multimedia. I like the idea of community based free software and want to get into system tweaking. I live in Norwich Best wishes Paul --------------------------------- Sent from Yahoo! - a smarter inbox.
