hello, while upgrading a kvm virtualization cluster from c6.4 to c6.5 and i am no longer able to control the migration speed. in c6.4 the default speed was the maximum bandwidth (1g in my case) and the actual migration speed was about 100MB/s. now in c6.5 the actual migration speed dropped down to about 25MB/s - 50MB/s, it varies and sometimes during migration of huge machines (36GB) i was at

Hello, I'd like to know if this is an hypervisor related problem or a libvirt one. I did this experiment: on VM I started watching a video on youtube. While video was in progress I started migration. Migration did not complete until video was not finished. I did another experiment: I installed a web server on VM. I then started an httperf stress test. As before migration did not complete

Hi list! I use Asterisk 13.14.1 from Debian repository on a DSL from Deutsche Telekom. Asterisk works well, but I have really often an high delay (I understand it since the other party speak some seconds before he hears my question and answer) and sometimes I hear an echo. I really don't know what can I check and what can be the problem. The problem exists since a very long time, but in the

Since a bit more than a year I run a Samba4 AD server on a Debian testing box. During that period I did update and dist-update the box about twice a week, and also did update and recompile Sambe, i.e. Samba and Debian Jessie are on their latest stage.

Hi, is there a way of simplifying the following code: G <- rep(NA,n) for(i in 1:n) { gj <- 0 for(j in 1:n) { for(l in 1:n) { for(m in 1:n) { gj <- gj+G.fun(XB[i]+p[3]*X[j,3]+p[4]*X[l,4]+p[5]*X[m,5],ff) } } } G[i] <- gj/n^3 } Thanks. Joaquim Santos
