I have recently seen an increase in traffic to one of my sites that is
hosted using UML. Previously, I had allocated 128Megs of RAM and 1 gig of
swap to each UML, but I never got close to touching the swap file. It
always remained at 0% usage. With the traffic spike, I have noticed
that I wil

Well I definitely wont do that!
Its not really a problem anyway, as I can monitor this based on IO
disk activity (I suppose).

Hi.
uml_switch is printing:
"send_sock sending to fd 4 Resource temporarily unavailable",
almost each second... I have 3 UML instances and the host
in the uml_switch.
Command line : uml_switch -tap uml0
I found an old thread with the same problem:

Sparse swap files are the recipe

Last I tried (in 2.4), sparse swapfiles were a no-no.

Why do you think they are scheduling issues?

If you use IP addresses on the same subnet for each UML session, no port
forwarding would be necessary.
What you do is, on the host set up a tun device specific to each
instance of UML. Like so: brctl addbr br0 (to add the bridge), brctl
addif br0 (i.

Nope. 64 MB per host. I have not had more than 10 per machine so far,
so thats 640MB used out of 1 GB. I am using tmpfs too...
Yes, swap is huge (300 MB). But it never gets used unless you do a yum

Hello,
Is there a way to allocate always the same pty to the same instance of UML ?
Like it is now, pty seem to be allocated in ascending order, but when I need
to start a bunch of UML's, it would be nice that they always get the same pty,
so that eg, if one of the UML's does not start, its pty n
