"yum update" did not update kernel on one box
This morning, I did "yum update" on my wife's box. It did not update the
kernel. I ran the command again, and there is a response that no updates
are available. Her box is a Compaq Evo D300v Celeron. During the past
couple of days, when I did "yum update", on my daughters box and mine
(Dell Dimensions), the kernel was updated and in the GRUB menus now,
there are two (2)

Backport uncertainty
I need to know of my version of Postfix supports a feature, given rh version numbers don't really tell you much I was trying to find an errata on postfix or anything to let me know the real version of it.
How does one deal with this scenario? Is there a source of info to determine this info?
Thanks!

Bug#464969: xen-hypervisor-3.2-1-i386: Linux mmap()/vmsplice() exploit causes memory map corruption in hypervisor regardless of domain privilege
Package: xen-hypervisor-3.2-1-i386
Version: 3.2-1
Severity: critical
Tags: security
Justification: DoS of entire system regardless of privilege
When running the exploit listed in bug 464953 [1], Xen's memory state
becomes corrupted and the hypervisor eventually crashes, taking all of
the domU's with it. As such, this breaks operational behaviour, so I have
marked this as critical.

local root exploit
I saw that there is a local root exploit in the wild.
http://blog.kagesenshi.org/2008/02/local-root-exploit-on-wild.html
And I see my centos box still has: 2.6.18-53.1.4.el5
yum says there are no updates... am I safe?

VMWare Server -- Which Kernel is Best
I read http://bugs.centos.org/view.php?id=2189
Summary: CentOS is not getting optimal performance in a virtualized
environment and on slow cpus
but I am not sure I understand the current best practice. Your thoughts
would be appreciated.
Options as I see them:
1. Run kernel-vm-2.6.18-53.1.4.el5 with clocksource=pit until the
excellent CentOS team builds the latest kernel into a VM kernel

io mode=native precisions
Hi,
Before switching to io mode=native, I wanted to check if there are any
disadvantages or potential problem with this setting.
I virtio-blk data plane required to use this setting effectively? (as
illustrated here:
http://blog.vmsplice.net/2013/03/new-in-qemu-14-high-performance-virtio.html)
Is there a requirement on the host kernel (eg minimum version)?
Thanks in advance

logging interim results using foreach/doMC
Dear all,
I am converting a large process to a parallel backhend using doMC and
foreach. Basically, I havea long list of input graph files and each of
them calls soem basic igraph package functions. I am parallelizing the
run, in order to save time. All works fine, and each %dopar% call ends
with a vector of results that at the end got fed into a data frame and
saved as a csv table.

Changing <on_reboot> in the domain XML file
Using virsh edit, I made the following change to the domain XML file:
<on_reboot>destroy</on_reboot>
But this appears to do nothing. The VM guest is Windows 10, and when
directing it to reboot, it still reboots, instead of shutting off the VM.
I was trying to work around some kind of a bug, somewhere, that started
happening after updating to Fedora 26 and qemu 2.9, where a
