Hi, Jeff told me to drop a note here about the following occurence:
Having compiled a 2.6.16.27 guest kernel with a bb1 patchset, I was unable to bring up an eth0 via tun/tap. The kernel runs well, but a command line of ./um2.6.16.27-bb1 ubd0=root_fs ubd1=swap_fs eth0=tuntap,tap112 mem=100M starts the instance well, but a command inside the instance of 'ifconfig -a' results in an 'eth2' device being ready to be brought up. I haven't found a way to bring up an 'eth0' or an 'eth1' device inside the instance. Has anyone had this kind of problem before? I've got no clue about its cause, this is what I found out until now: - The problem seems to be independent from the Host Kernel. Using the above Guest Kernel, the system will always prepare eth2. - The problem seems to be independent from most of the other options in the Kernel config as there are statically linked, network options etc. - The problem is not (!) present with older Kernels. I did run some tests with other Kernels, the following ones failed to bring up eth0: 2.6.16.27 with bb1 2.6.16.9 with bs2 The following versions were ok in bringing up eth0 as usual: 2.6.14.3 with bs3 2.6.13.4 with bs5 - I haven't tried non-SKAS3 usage yet As Jeff told me yesterday that there was possibly no change in that region of the UML code, I suspect that any kind of change in the recent Kernel sources has caused this artefact to show, sadly I haven't got the faintest idea of Kernel development myself, so I'm writing this to the devel list.
