[Xen-ia64-devel] Re: blkbk/netbk modules fail to load on fedora xen/ia64

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, Aron and all

I can solve this problem by using dom0_mem=1G.
FC6 test3 uses many daemons and services.
Because booting xend is late,
we fail insmod blk/netbk if dom0_mem=512M(default size).

We may have to change dom0_mem of FC6 default to 1GB.
But I think the best fix is (1) statically link the modules.
(Because all kernel-xen need blkbk/netbk and xenblk/net. 
ide module is also static link. And because xen community member test
the statically linked modules, I think the statically linked modules is 
stabler than the dynamic linked modlues.)

Please give me some comments.

Best Regards,

Akio Takebe
