NetBSD/amd64 XEN3_DOMU from
When changing Network type to "VM" from "Network0" or vice versa
on Citrix XenServer, kernel panic with the following messages
(manually copied).
I am using NetBSD/amd64 6.0_BETA2 (XEN3_DOMU kernel) xva image from
on Citrix XenServer 6.0.201.

panic: kernel diagnostic assertion "(entry->flags & UVM_MAP_STATIC) == 0" failed : file "/usr/src/sys/uvm/uvm_map.c", line 2218

dump to dev 142,1 not possible

Install Citrix XenServer 6.0.201 to server machine and install its XenCenter to
Microsoft Windows client machine.
And connect to XenServer from XenCenter.
Import NetBSD_amd64-6.0_BETA2.xva from .

Run the VM, and on "Networking" tab, change network type.


I have no idea.
