I'm moving the VM server hard drives to a new computer donated by Kenny
on Saturday morning. Downtime will depend on how fast I am with a
screwdriver.
Kenny has donated:
* A Cooler Master case with several big fans and power supply
* 2x4G of DDR3 memory
* Motherboard is Asus M5A88-V EVO
http://ca.asus.com/en/Motherboards/AMD_AM3Plus/M5A88V_EVO/#specifications
* CPU is AMD Phenom II X6 1055T, which has 6 cores, 512k L2 cache per
core, a shared 6M L3 cache, and AMD's virtualization extensions
Thanks!
I'm going to see if I can buy another 2x4G DDR3 (~$90!) tonight or
tomorrow morning to max this thing out at 16G. (to be paid back to me
later by selling off the old VM server, the other proceeds of that I'll
have Skullspace hold in trust to help pay for whatever upgrade comes next)
We'll probably want to start thinking about our next generation board
right away given the memory limitation. (I still suspect it is enough
with room to spare for everyone in the server room at present)
On a different day I'm going to take advantage of the VT extensions that
this will give us and make the swtich from VirtualBox to qemu-kvm with
libvirt and virt-manager.
Virtualbox is able to take advantage of the virtualization extensions,
but they perform better when there's a single hypervisor.(this is
explained very well in the virtualbox docs)
Virtualbox on separate user accounts makes this not so and I don't want
to switch to a single shared account model either.
We can use libvirt with separate user accounts with a single hypervisor
because it's just a matter of putting each user in a libvirt group
permitted to work with it -- so we'll also be able to see what each
other is running.
Justin appears to be our only 24/7 user of Virtualbox (I moved him
Wednesday night). Do any of the other users want me to migrate their
virtualbox VM's to qemu-kvm/libvirt immediately when I do this?
(there are also several users that I had set up Linux containers (LXC)
for -- those will be be fine)
After that I'll start trying to persuade the other server owners
mentioned in a previous post to go for a migration.
Mark
