being as we're all fully paravirtualized guests, we're okay;  no reboot is required.  



the most relevant bits to prgmr.com follow.  Note, prgmr.com only offers paravirtualized guests, so as far as I understand, this isn't a problem for us. 


A buggy or malicious HVM guest can crash the host or read data
relating to other guests or the hypervisor itself.


Xen 4.1 and onward are vulnerable.

Only x86 systems are vulnerable.  ARM systems are not vulnerable.


Running only PV guests will avoid this vulnerability.
