I do not think that this is possible without an additional device in the
UML itself.
In fact, if you want two processes in two different UML instances to
communicate in-between themselves you should aim at a UML device. The

Hi:
I wrote an IPC mechanism as a Linux kernel module. The access to their

Hi,
I would like to know if the User Mode linux creates (and initialises) 'struct
uml_net_private' for every interface device on it? To be specific, if there are
multiple l2tpv3 tunnels on the UML, does it warrant the creation of as many
'dev's, and consequently associate it with a corresponding
Hi list,
Some benchmarks (current version, I believe this can do more once it

Hi Richard, hi list.
I have found a couple of minor issues which have crept up during porting
from 3.3.8 to 3.12-3.15 (I originally wrote all of the improvements for
3.3.8/OpenWRT).
I will reissue the patchset with these fixed sometimes this week -
descriptions of issues/coming fixes inline.

Patch dependencies:
[PATCH v3 01/10] Epoll based interrupt controller
Full redesign of the existing UML poll based controller. The old
poll controller incurs huge penalties for IRQ sharing and many devices
setup due to the device list being walked twice.

I have been trying to bring the openswan nightly build system up again
on a newish system. I started these scripts back in 2002, and it has been
running
on and off for many years, and many kernel revisions.
I started this most recent effort work when 3.5 was stable, so my guest
kernel is a 3.
Great to know this, thanks for keeping it up!

KVM is *much* faster than UML and *much* less hacky. :-)

But then there's a fundamental question of whether KVM has similar
semantics.
UML was incredibly useful to my project since it ran a whole "kernel +
processes" in user space.
Now i'm confused as to whether I need to change my work so that it works
with KVM (I'm trying to read thru KVM docs to under

so you mean to say that KVM is preferable to UML?

The book (2004) states that work was going on for hardware assisted virt.
Has there been progress on it? Where do I find information on it?
The UML source tree still comes with the original modes of operation.

I'm wondering whether this was useful?
Is there any other testing that I can do to help the cause, and to help
fix this problem?

I have experimented further with the network related crashing problem that I
have had for some time with UML.
I have been using 3.8.0-rc3 UML kernels with Debian root filesystems.
I have been running two UML instances side-by-side on the same host and
communicationg via mcast networking.

CC'in Al, maybe he has an idea.
Does the crash only happen
I note that my message sent yesterday ended up heavily truncated, so I have
turned on the line-wrap for this one. Sorry about that.
What I was trying to say is that I can repeatedly crash UML by exercising the
networking heavily as a result of rsync'ing data to and from.
I also said that I have
I have problems with UML crashing that I believe are network related, because
the crash happens whenever I try to make heavier use of the network connection
to rsync more significant amounts of data from the UML.
It may or may not be significant, but when I am rsyncing from one UML to
another,
