Subject: [gentoo-user] Xen-4.1 + Gentoo-Sources 3.0.6 in Dom0 = no blktap

1 Hi,
2
3 I am using Xen 3.4.2 with xensources for Dom0 and DomU at the moment.
4 Now I tried to upgrade on a testsystem to 4.1.1 and a 3.0.6 Kernel
5 for Dom0. The problem is, since there is no blktap driver in the
6 3.0.6 Kernel I have to fall back to file:// instead of tap:aio for the
7 disks for the guests. Anybody knows a way around this?
8
9 Also I tried a 3.0.6 as a DomU kernel but this panics during boot time
10 with:
11

13 margin is 60 seconds).

26 Somebody can hint me, what in the Kernel-Config of the DomU kernel
27 might be wrong here? Xen-Sources 2.6.38 boots in this setup.
