Enterprise team shot this issue up to me today which I hadn't seen before. There was a hung VDI VM in our Xen Server 6.5 farm that refused to boot. Every time it would attempt to power up, it would fail with the error of "VDI Not Available." Typically this occurs if a VM hangs … Continue reading Citrix Xen Server 6.x Error: VDI Not Available

Obviously you want to push the bash updates to all your servers sooner rather than later and you have no reason not to as it's a non-disruptive update. A user in the sysadmin channel on FreeNode … Continue reading Shellshock continued!
It's been an interesting year in terms of finding massively exploitable Linux issues. Heartbleed was a nightmare that caused several late and long nights for IT teams across the entire globe.
