Start simple :
- 1 vCPU per domU, try to let one for dom0, specially if it manages a complex
storage (soft RAID, DRBD, LVM, iSCSI...)
- Let at least 512Mo for dom 0, spread the rest on your domUs depending on
what they do. Good to know, you can change the memory allocated for a domU
online !
Make some tests, load tests.
If you know or you see that some tasks are slow because they can't be
parallelised, add a vCPU to the domU.
The essential here, is to know what your domUs will really do, and how much
you planned.
Thank you for the tips. Now, I just check the output of my "apt-cache search xen" on my Debian GNU/Linux Etch AMD64 and I got many outputs. What are the packages I just need to setup Xen images? Like for instance, I'm confused which linux-images shall I install between the two (2) because they both have the same description:
linux-image-2.6.18-5-xen-amd64
linux-image-2.6.18-5-xen-vserver-amd64
Also, what is the difference between xen-linux-system-2.6.18-5-xen-amd64 and the xen-linux-system-2.6.18-5-xen-vserver-amd64 and which of these two shall I install?
Please advice.
Thank you in advance.
