Re: [Xen-devel] Possible memory leak in qemu-dm (qemu-dm swapping 20GB+, adding 2gb+ per day)

Sorry, this is a bit of a newbie question. Can I download xen-utils-4.3 for jessie (http://packages.debian.org/sv/jessie/amd64/xen-utils-4.3/download) and use that qemu-dm? Or will that wreck all kinds of mayhem.

FWIK debian Sid xen 4.3 packages not add qemu traditional anymore but use only the upstream from qemu debian package (now at version 1.6.1).
For now I not tested new xen debian package but I tested qemu debian package and is working and full features (xen upstream qemu instead have some features missed).


I’ve compiled my own qemu based on qemu stable, just need to get my VM cfg to accept the device_model_override (appears to be ignoring it for now)

Assuming my Debian 7.0 with xen 4.1.4 uses qemu-xen-traditional then yes. Otherwise I’ve observed it in default xen qemu for debian 7. Currently all mine (and ilon@xxxxxxxxxx’s) qemu-dm instances keeps growing, adding several GB in swap per day. Then dom0 runs out of swap and the qemu-dm segfaults and I have to xl destroy it. Then I start the domain again and qemu-dm starts growing in swap.

Can I help in the process of confirming this bug in qemu-xen-traditional?

Do you mean to say that you have observed qemu-xen-traditional's
qemu-dm growing, as described in the bug report ?

Thanks,
Ian.
