[Xen-users] talking about usb, cdrom, cpu and vcpu
hi, i have many questions about my doubts: i use xen 3.0.0 can i manage usb with domUs? if yes how? how can i manage cdrom? who and how manage who can access it? dom0? i didnt find on manuals documentation about cpu... i made some try... with the conf file of domU i can set one cpu with cpu="n", i tried to do cpu="1-3" but it takes only the 1st... not from one to third... hoc can i do that? then... i cant change the number of vcpus of a domain running, with xm vcpu-set domID #vcpu ... the command seem to work but with xm vcpu-list i dont see my changes... so i have to reboot the domU changing vcpus="n" for make it change... xm vcpu-pin domId vcpuID #cpu works great... any documentations about it?

>> can i manage usb with domUs? if yes how?You''ll be able to dedicate an entire USB controller to a domain using PCI device assignment in 3.0.2... USB virtualisation will appear some time in the future.>> how can i manage cdrom? who and how manage who can access it? dom0?You can give guests access to it if you want, as a normal virtual block device. But it''s not a particularly convenient way to work - for instance, they won''t see it as a normal CD-ROM, won''t be able to eject it, won''t be able to drive a writable CD-ROM device... (nb. VMX guests have less limitations regarding CD-ROM access) HTH, Mark _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
