From: Nate Studer <nate.studer@dornerworks.com> Add a utility function to update the rest of the timeslice accounting fields when updating the timeslice of the credit scheduler, so that capped CPUs behave correctly. Before this patch changing the timeslice to a value higher than the default would result in a domain not utilizing its full capacity and changing the timeslice to a value lower

Hi all, Since Xen 4.2.0, users can change time slice of the scheduler at runtime via xl command line, a very nice feature. However, it is not *correctly* implemented. Problem description -------------------- say you set the ''cap'' of one VM to 50 (a half core), -when setting the time slice to be *greater* than 30ms, the VM gets much *less* CPU cycles than its allocation -when

Hello, This small series deals with some weirdness in the mechanism with which the credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are available in the changelog of the first patch. The new approach has been extensively benchmarked and proved itself either beneficial or harmless. That means it does not introduce any significant amount of overhead and/or performances

Hi, I am trying to install openxencenter to control my VMs I followed the instructions but when I tried to start it I got:  File "window.py", line 44, in <module>     import gtkvnc ImportError: No module named gtkvnc does any one face this problem before. I tried to comment the import line and xencenter started but console tab is not working and it is lookoing for gtkvnc module.

Hi, I am a newbie, i wanna know how to implement database driven Tree structures in RoR? Is there any direct support available or should they be implemented in Javascript ? Any tutorial link if provided will be of good help Thanks in advance Sathya -- Posted via http://www.ruby-forum.com/.

Hi, I was trying to add some printk in the credit scheduler to see how it works, but the printk seems not working. (it gives no output) But when I add printk in scheduler.c, it works pretty well. Does anyone know why? do I need to change some configuration file or something? Thanks very much! Best! Yours, Sisu _______________________________________________ Xen-devel mailing list

================== STATUS ================== I do the heavy load test of create/destroy. CREDIT scheduler(cshed_schedule) checks BUG_ON(!vcpu_running) at the end of code. It makes error. The reason is that atomic_inc(&v->pausecnt)@vcpu_pause() is called without lock. (spin_lock(&schedule_data[cpu].schedule_lock)) This lock-less "pausecnt" makes vcpu_running state changing

Hi John, Thank you for the reply. Actually it was setup like this by another member, who left the team/company recently. Now it came to me to handle that responsibility. That's how I got in to this. At present I am not able to migrate/upgrade immediately. Because it sends emails around 100K+ emails everyday and I do not want to disturb that. Coming back to your question, Actually the

Hi All, I need your help on one of the issue in Dovecot. I have the dovecot version 2.0.9 installed on RHEL linux 6.10 version. It's a single/standalone Live server. Now I have created another server with the same configuration for the resilince purpose. I also tested and I am able to send the emails to both of the dovecot servers separately/individually. They are working fine. Now I have

Hi Aki & Dovecot team, Just continuing with the previous discussion "Migration from one server to 2 new servers". Hi, I have tried the same way as per your suggestion. But it's throwing an error. ------------- [root at production2 log]# doveadm backup -a All -R -u kishore at test.ba.com imapc: dsync(kishore at test.ba.com): Info: imapc(production1.baplc.com:143): Connected

I seem to recall a post a while back where, due to the age of the remote end, the remote side command had to be entered in the command executed on the local side. Do you have dsync on the 2.0.9 machine? > On Jul 27, 2020, at 4:16 PM, Kishore Potnuru <kishore.reachme at gmail.com> wrote: > > This is what my understanding.

Well that option set still doesn?t look correct? Here is the doveadm option set from my 2.2.2 server which is several weeks\months before 2.2.36?

Fair enough but the command snippet I posted was taken directly from your earlier post dated Mon Jul 27 23:11:06 EEST 2020 and it does say ?production1??I just double-checked as well... FWIW?the server order in the command you just pasted is the exact reverse from the Jul 27th post I mentioned above? Here you appear to be exec?ing the command on prod2 and trying to pull from the remote of prod
