Considering that the technic of SPDK + QEMU is making progress toward maturity. Personally I'd like to do the integration work. Not sure somebody would mind to give me some clue on that? Because I'm not familiar with libguestfs code structures. Thanks, Bob

To me, the advantage of nvme is that it provides more than decent performance on unmodified Windows guests, and thanks to your vendor extension can be used on Linux as well with speeds comparable to

Thanks for the information, I am unclear how to implement the winbind 'rid' backend. I've identified that winbindd is not operating on my demo server (fresh installation of Ubuntu 16), and am looking for some assistance if possible. 1] 'apt-get install winbind' informs me that the package is already installed (v4.3.9), yet it is not operating; 2] Lsof -Pnl +M -i4 provides:

Hi Friends, I encountered a strange issue. I am running Asterisk 11.8.1 on Cent OS with no firewall running. It has 3 NIC interfaces. in my sip.conf I have allowguest=yes bindaddr=0.0.0.0 udpbindaddr = 0.0.0.0 But my Asterisk instance does not pick the call at all. When I check the listening apps using lsof -i I get asterisk 3046 asterisk 7u IPv4 1191172 0t0 TCP *:5038 (LISTEN)

Hi! On my FreeBSD 12.0-RELEASE-p7 server I was unable to retrieve the correct information from my two UPS. Every time only the first UPS will returned when I entering "upsc apc900" or "upsc apc901". I don't know why (Bug or configuration issue on my side?!). I have downloaded the latest source code and with my "patch" I was able to get the right information

Hi Alberto, With systemd it will be as easy as creating additional unit files ( one for > each memcached instance) with its corresponding config file. That should > allow to stop / start / restart each memcache instance individually while > also being systemd compliant. Thanks for the info and for the examples. It really does make sense the way you explain it. Thanks for letting me

Surprisingly, I can reproduce even by hotplugging a DIMM instead as well - that's good, so it's not related to virtio-mem, lol. Seems to be some QEMU setup issue with older machine types. Can you switch to a newer qemu machine version,

Occasionally, all of our directors get stuck in an endless loop. Likely triggered by some network event, but I haven't been able to isolate exactly what triggers it, and am unable to reproduce at the moment. When this happens, it makes the dovecot/director process on all directors unresponsive, making login impossible. Restarting dovecot "fixes" it. Here's the info collected
