similar to: poor performance with dom0 on centos7

Hi All it is possible to tune dom0/domU for better IO/network performance? Since I have changed to Cenots7 dom0, I have a really poor IO performance inside a PV VM. I have already done what is described on http://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance It is better now but still significantly worse than with centos6 dom0 my settings: xen parameter: dom0_mem=1024M cpufreq=xen

Hi Im now pretty sure the problem is the DomU with NFS Server. If I write on a NFS share from other Host (bare metal or other vm) then I see on my NFS server nearly the whole time 100% io at [jbd2/dm-5-8] process... If I write on a SMB share (same partition as nfs share) from other Host then it is a little bit better but still ever and ever again 100% io load If I write a 1GB file on the

Hello, Recently, I've spent the last few days trying to get some unix client boxes to authenticate logins via winbind, so all of our unix system accounts can be maintained from active directory. So far, everything is working, and users can authenticate into the system, but they are assigned random uid/gid values, based on the smb.conf as well as the internal winbind_idmap.tdb file.

Hello, I recently upgraded from Dovecot 1.1.8 to 1.1.14, and I've started to get errors I never got before. Specifically, I'm getting "Mailbox is locked, will abort in xx seconds" errors. My mail client (mutt) will just sit there in the background (presumably in IDLE) and randomly will show this error (I THINK it has something to do with delivering new messages to the

This issue I am encountering seems to only happen on multi-socket machines. It also does not help that the only multi-socket box I have is an Romley-EP (so two socket SandyBridge CPUs). The other SandyBridge boxes I''ve (one socket) are not showing this. Granted they are also a different model (42). The problem is that when I run ''perf top'' within an SMP PVHVM guest,

Hello, I observed that a configuration where dom0 vcpus were pinned to a set of pcpus in the host using dom0_vcpus_pin and the guests were prevented from running on the dom0 pcpus (here called "exclusively-pinned dom0 vcpus", or xpin) caused the general performance of the guests in a host with around 24 pcpus or more to increase during bootstorms and high density of guests, even

Hello all, I seem to be having a problem with SASL. It doesn't seem to work with Outlook. Upon searching a bit, I found that I need to enable "login" for auth mechanisms.
