Xen netback driver: With TSO enabled on netfront, we can generate longer
mbuf chains than the Linux netback is able to handle. I have an ugly patch
for this on EC2, but andre will be fixing this better in the near future.
For now I recommend
# ifconfig xn0 -tso
unless you need mul
ess; have you made any bug fixes after
your pvhvm_v7 which would explain why tasting disks was hanging?

Done, ami-95177dfc in us-east-1.
This is now booting successfully on cr1.8xlarge; are there any other instance
types I should test? I don't know which Xen versions you have deployed across
the entire fleet.

Now the only step remaining to make FreeBSD/EC2 pure "straight off the
RELEASE ISO" FreeBSD is to get Xen HVM functionality into GENERIC.

Depending on feedback from freebsd-xen@ I hope to send this to freebsd-current
for wider review later this week and then commit it before the FreeBSD 10.0
code freeze starts on September 7th.

How do you intend to have Xen HVM work in the GENERIC kernel configuration?
Will you be adding 'options XENHVM' to GENERIC?

Also any PRs talking about FreeBSD/i386 Xen/PV can probably be closed with "yes,
that code is horribly broken and needs a complete rewrite, don't even try to use
it for now".

S received.
Under exactly the same Xen configuration except with SR-IOV turned off and
EC2 presenting a Xen netback to us instead, the DHCP works just fine.
Has anyone managed to use {FreeBSD, SR-IOV, ixgbe, Xen}? Was any magic
necessary in order to make it work?

Are there any diagnostic tunables/sysctls I should try turning on? Since this
is in EC2 I'm unfortunately limited to "printf-style" debugging.

This is Xen, running in this case using HVM: http://aws.amazon.com/ec2/

You want to switch to using HVM with PV devices. That should be a simple
tweak to your Xen configuration, and then you'll be able to use a GENERIC
kernel.
