than saucy for this,to avoid hitting a possible bug 1199349 as Serge
pointed out earlier and that I was also able to reproduce. Thanks

Thank you for the comments.
The failure occurred with 3.10.0-2.10-generic as well for me. Please see the
log that's attached in comment #11, and that occurred on my local raring
machine. I can reproduce this issue on my local machine once every 4-5
attempts. As given in the description, the
Can you also install and run debsums -sa on the affected system?
I recognized the name aldebaran as the one that gave us some
interesting random data corruption a while back (without any obvious
entry in dmesg which made things confusing), so I'd like to verify the
VM is in perfect condition
I'm still unable to reproduce this. I have tried with a precise host
using bridged networking with 3 other VMs running (pretty much the limit
I can do here) and rebooted the saucy VM with the specified networking
configuration 10 times without incident.

Yes I can confirm that dhclient: execve (/sbin/dhclient-script, ...):
Permission denied error occurs only on VM's which has this connectivity

I have been able to reproduce this issue on a raring host as well on my
local machine. Please find attached the log of that failure.
Note: Please note that the latter part of the logs may suggest the
network is back to normal. This is because I manually did sudo ifdown
eth0 and sudo ifup eth0
Using 3.10.0-2.10-generic (the reported kernel is 3.10.0-2.9-generic
though), I still cannot reproduce this. I updated
/etc/network/interfaces to use the above and removed any hook files from
my VM. The netowrking comes up fine. I modified run_hooks() in /sbin

Are you using a special dhnsmasq/dhcpd configuration? Do you have a

disabling networking in network-manager and adjusting
/etc/network/interfaces to use 'iface eth0 inet dhcp' and using 'ifup
eth0'. I also tried by using 'dhclient -sf
