RE: [Xen-users] Some basic questions

Hi,

* Add dom0_mem=1024m on the kernel line of your bootloader config file
(/boot/grub/menu.lst if you're using grub)

* The number of domU's doesn't actually affect the amount of memory... All
you need is some space for caching. So 1GB should be sufficient.

* Don't know myself. I always specify the option :-)

* Use vlans to isolate traffic

Cheers,
Jeroen

Subject: [Xen-users] Some basic questions

Hi,

I'd like some clarifications:
  - Is it possible to limit the use of RAM on Dom0? How?
  - How many Ram should i give to the Dom0? Does it depend on the
number of the DomU?
  - If i don't indicate the options about the "cpu" and "vcpu" on
DomU( when i've got 2core-duo or quand-core), how is the manner of
using the  CPU ?

i'd like to put the Xen Server on the DMZ:
  - How could i protect my Dom0 to avoiding any access to Dom0 from
any DomU ( on Dom0, there will be no services except SSH)? Perhaps
some Iptables rules?

Thanks in advance for yours answers.
