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. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
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 -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of ko0nz Sent: vrijdag 11 januari 2008 12:06 To: xen-users Subject: [Xen-users] Some basic questions Hi, I''d like some clarifications: - Is it possible to limit the use of RAM on Dom0?

hi Jeroen, thank you for your return. - 1Go of RAM for the Dom0, it''s too much...,i think when you''ve got 2Go RAM :) - i use vlan to isolate the traffic from the local network but i''d like to do more the Xen Server...
