Hello everyone,
I noticed some unexpected behaviour today while setting up an OpenBSD
domU (HVM, of course).
Usually I just emulate a e1000, because the default gives me constant
watchdog timeouts (this seems to be well known).
The new thing though is that:
- with e1000, install will hang when entering networking parameters.
- if done manually when the system is running, the VM will hang when
upping the interface.
- setting an IP while the system is running results in the same
behaviour as inputting it during install (ifconfig will hang)
- with other drivers (that the fxp driver on obsd recognizes), upping
the interface immediately reboots the VM.
The one thing differing here (besides hardware) is the Xen version: I
usually run 3.3.2 (the dom0 is NetBSD -current), and this is 4.1.
I have some VMs running OpenBSD on Xen 3.3.2: this issue isn't present
(therefore I'm assuming it's somehow related to Xen 4.1, altough not
100% sure!).
Using xm, not xl - though it shouldn't matter?
If anyone is interested in troubleshooting/confirming this (install a
obsd hvm domU, try to configure the network on install - config provided
in the end of the email -- you'll need install49.iso from a OpenBSD
mirror/ftp site: for 4.9/amd64, it's
ftp://ftp.openbsd.org/pub/OpenBSD/4.9/amd64/install49.iso)
Since this is an ongoing project and I need the VM setup, I only have so
much time to try to get to the bottom of this. Will have to revert to
3.3.2 in a day or two otherwise.
For any reply: please CC me, as I'm not subscribed to this list.
Best regards,
Hugo
