Re: Enabling VIMAGE by default for FreeBSD 11?
Something that just popped up here in local hacking is ensuring that all the vnet state is correctly torn down _after_ the system has finished with things that reference it. For example, having the vnet state torn out from underneath say, active TCP timers that haven't yet been cleaned up. Is that fixed or not a problem in -HEAD? -a ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to freebsd-virtualization-unsubscr...@freebsd.org

node-nd_ID = (*(__typeof(vnet_entry_nextID)*)
(__curthread())-td_vnet))-vnet_data_base) +
(uintptr_t)vnet_entry_nextID))++;
On my system, td_vnet was not initialized, so that was causing the kernel
panic.
Is the attached patch OK to commit to -CURRENT, and then after some time MFC
to stable/9?
With this patch, my system can boot with VIMAGE enabled in the kernel and it
does not crash.

Re: Avoid sharing interrupts in FreeBSD under ESXi
... you mean if mpt and em share an interrupt, things get wedged? adrian On 18 June 2013 01:16, C. L. Martinez carlopm...@gmail.com wrote: Hi all, First, sorry for the cross-posting. I have installed a FreeBSD 8.4 vm under an ESXi 5.1 U1 server.

Is it possible to avoid to share interrupts in FreeBSD when it is running as a vm? Exists some kernel option to resolve this (via sysctl or compiling a new kernel)?
