Re: [uml-user] Hanging UML

[Carl P. <ca...@bo...>]

The only issue is that I'm not allowed to play with the host's kernel at =
all
(unless I want to land myself in hot water), which is mostly why I'm usin=
g
UML.

I'm allowed to dowload a full 2.4.24 kernel source into my home directory
and build UML there.

But from what I understand it's only a problem if I'm running hostfs AND
then run updatedb whatever that is.  Can't I just not run updatedb?

Alternatively I could limit what's mounted by hostfs?

Thanks,
Carl

Yes, it is exactly what Jeff Dike means. But I'd suggest something simple=

before ( see below)

No, well, the 2.4.19-5um is 1 *year* and half old and has LOTS of bugs! S=
o
please recompile at least a 2.4.24 guest kernel!

If you use an host older than 2.4.25, then you must upgrade it. There is =
a
bug
in the host causing that behaviour: it happens when you run updatedb and =
the
host /dev/shm dir is reachable through a hostfs mount.

So, at least 2.4.24-1 for the guest and 2.4.25 for the host. A 2.4.26 gue=
st
compiles with little changes (search 2.4.26 onto this list to find the
patch). If you use 2.4.24-2 patch, disable HUMFS, or it could not build.
