[Xen-devel] Is there an issue with turning off "scrubbing free RAM" on boot with Xen 4.1.3



Thank you in advance for your support!


Our HP Xen 4.1.3 servers have 1TB of RAM, each Xen servers take 20 minutes to boot largely due to the "scrub free RAM" phase. If/when we have dom0 failures and HA kicks-in, we would like to reduce the boot time to make the resource quickly available, perhaps using the no-bootscrub attribute in grub.conf.


Could you please share your comments about turning of RAM scrubbing, i.e. have you seen any consequences, security issues and/or threats, red flags, etc...?


We have asked the same question at the commercially supported Xen forums, i.e. Oracle and Citrix, as well as to each aforementioned support team, and have not received a lick of meaningful information.
