kernel Panic on desktop
I arrived at work this morning to find that my desktop unit
(CentOS-6.6 KVM) halted with a kernel panic. I am not conversant with
any way to save the console display in this case and there was rather
a lot of text. I jotted down a few notes and power-cycled the unit to
restart. which it did and I am using now to compose this message.

KVM kernel panic when additional virtio disks added
CentOS-6.6
virt-manager 0.9.0
I have cloned a template server with a 32GB virtio HDD already defined
and am attempting to add additional virtio disks. The basic cloned
system boots without error.
If I create a virtio disk with 32000/32000 megabytes I can add it and
the system reboots; providing that I do not first create a partition:
fdisk -l /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03

CentOS-6.7 Passing delayed shutdown via ssh command line argument?
If I log into a host via ssh from my workstation then I can enter this:
shutdown -r +90&
and log out. The shutdown command will continue in effect and will
activae 90 minutes later.
However, if I do this instead:
ssh -t host.domain.tld 'shutdown -r +90&'
then the shutdown command does not remain in effect. Why is this so
and is there some way to achieve this?

CD-Mount on CentOS-6.7
When I load a blank cd into the optical drive on my CentOS-6.7
workstation I am not getting any window or visible mount action on my
Gnome desktop. Formerly, when I mounted a writeable media in this
drive on this host I would see a nautilus style file browser window
open with inducements to add files.
When I visit /mnt I see nothing:

CentOS-6.7, kvm bridges, virtual interfaces, and routes
I have been looking at this problem on and off for a considerable
period. Given my lack of knowledge I have been unable to resolve this
quickly and in consequence it has been constantly shoved to the
background as other issues arise.
Here is the situation:
I have two dual-homed kvm hosts both running CentOS-6.7 and
identically configured. These are connected to the same LAN segment

Kernel panic when adding partitioned virtio disk
I have a cloned kvm (that I can now get started following a shutdown
and reboot of the hypervisor host). When it starts with its original
virtio disk there is no problem. If I create a virtio disk and add it
via virt-manager it also boots without issue, although one cannot see
the new 'physical' disk. If I shutodwon the kvm guest, partition the
new virtio disk, and reboot the guest then

I changed the entries in smb4.conf (smb.conf) to this:

dns update command = /usr/local/sbin/samba_dnsupdate
nsupdate command = /usr/local/bin/samba-nsupdate -d -g

Why does freebsd put these things in /usr/local/etc/? Some questions have
answers that are not worth the effort to know.

I did catch that error earlier. But it makes no difference. samba_dnsupdate
