Hello,
I stumbled across something I find strange, and I'm not sure if it
is a bug or not, but if it is not then still it has some unfortunate
repercussions.
I have one guest which does a decent amount of traffic (100–200Mbps
constantly) and it was brought to my attention that the bandwidth

Thanks for getting back to me. I will try this in the next day or

Hi,
I have a Debian jessie server with an LSI SAS controller using the
mpt3sas driver.
Under the Debian jessie amd64 kernel (linux-image-3.16.0-4-amd64
3.16.36-1+deb8u2) running under Xen, I cannot put the system's
storage under heavy load without receiving a bunch of "swiotlb
buffer is full" ker

Ah, okay, thanks. That is what I feared.

Hello,
Please forgive me if this is a naive question but I do not know this
low-level stuff very well.
If the ability of the toolstack to dump a guest's memory (e.g. xl
dump-core) were disabled on the hypervisor side, would there be any
other way to do so from dom0 without rebooting the machine i
