Running Dovecot 2.0.8 on 32bit Centos5.5. The machine is a VMWare ESX VM. I'm seeing a lot of warning messages in syslog as follows: 2011-01-14T11:45:37.315917+08:00 imap4 dovecot: imap: Warning: Time jumped forwards 105 seconds 2011-01-14T11:46:00.598006+08:00 imap4 dovecot: imap: Warning: Time jumped forwards 106 seconds 2011-01-14T11:46:25.364405+08:00 imap4 dovecot: imap: Warning: Time

Hello - I've combed the wiki and archives a bit and can't seem to find what I am lookng for. It seems that BlackBerry Internet server has an issue with IMAP accounts along with IDLE and concurrent connections. Please see the following link (sorry it's fairly long):

Amazon (or perhaps Amazon's configuration of Xen) forces a machine to come up at run level 4, regardless of what's in /etc/inittab. I've looked through /etc/rc.sysinit and /etc/rc.d/rc, to determine which (if any script) looks at /proc/cmdline and forces a particular run level, but to no avail. It seems that /sbin/init does the forcing. Can anyone confirm that /sbin/init reads

Does anyone have a standard install of CentOS virtualization grub.conf working in a proven state with the FALLBACK option? If so, can you post your grub.conf? I mistakenly updated to 5.5 and am concerned about nvidia driver comments in the release notes. I did not have protectbase configured on this machine. It is a remote device that will reboot.

to convert hvm to pv guest, I have followed the direction( link<http://pastebin.com/f6a5022bf>) in Xen-Users Common Questions Guide. It says the first step is "install kernel-xen with correct initrd" After "yum install kernel-xen" was executed, following errors were showed: WARNING: No module xen_vbd found for kernel 2.6.18-164.15.1.el5xen, continuing anyway grubby

Hi, The Gentoo-Wiki about Xen suggests, to add "-mno-tls-direct-seg-refs" to CFLAGS and to recompile the whole system. So it seems, NPTL will work without problems (and without performance drawback) after that. Sweet! But i carefully read http://wiki.xensource.com/xenwiki/XenSpecificGlibc, and it says: "On 32-bit x86 platforms, Xen uses segmentation to provide protection of the

Hello, We have default xen 3.1.2 on centOS 5.5. We now want to upgrade xen 3.1.2 to xen 4.0.1 while using the existing dom0 kernel (2.6.18).

I am running Xen 4.0.1 with a 2.6.18-194.32.1.el5xen CentOS Dom0. I built and installed the Xen binaries from source. The systems boot successfully however I am having issues bring up DomUs.

Hello, I created a paravirtualized Debian Squeeze guest (using virt-manager), after completing the initial setup I was asked to reboot, in order to finalise the installation. The guest startup breaks down with the error message: Error starting domain: POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: Boot loader didn''t return any

I built a couple new servers on SLES11 because I needed to use USB. Since SLES11 has xen 3.4 packages that seemed like the way to go. I''m questioning the stability of the two new servers compared to my SLES10SP2 servers. I''m also questioning the performance of Windows domUs. On Thanksgiving day one of my SLES11 servers running 7-8 domUs crashed and restarted three times. Being

Hi all, I am in a bit of a fix here, I have several Guests paravirtualized running on a Dom0 that is currently running the 2.6.18-92.1.22.el5xen Kernel. All my guests (administered by different people) have subsequently been updated to later versions of the kernel (namely 2.6.18-164.el5xen or 2.6.18-128.4.1.el5xen). Ones that are still running are using the Kernel 2.6.18-128.4.1.el5xen while

On the subject of kernel updates: I had my install kernel (2.6.18-8.el5xen) and 2.6.18-8.1.8.el5xen on the box. I was unable to originally boot the update (8.1.8xen) because of the 3ware driver issues (I needed to use a driver floppy at install time). I jumped through some hoops (which I am struggling to understand) with weak-updates to get the 2.6.18-8.1.8 kernel to see my raid devices, which

Hi, I was trying to install OCFS 2 in my Oracle Linux 5 Machine.

This bug is reported only on the VM's with CentOS 7 running on on VMware ESXi 5.1. The vSphere performance graph shows high CPU consume and disk activity only on VM's with CentOS 7.
