Change Xenserver Pool Master

Change Pool Master via CLI

First disable high availability:
xe pool-ha-disable

Now list your XenServer hosts:
xe host-list

Using the list above, designate a new pool master by supplying the uuid associated with the desired host:
xe pool-designate-new-master host-uuid=

You’ll probably lose connection to the pool at this point, but that’s normal behavior. Once XenCenter reconnects (this should happen automatically), it’s safe to re-enable high availability:
xe pool-ha-enable

Google users targeted with malware-laden “Suspicious sign in” notices

Emails purportedly sent by the Google Accounts Team warning about a prevented “suspicious sign- in” have been spotted targeting Google users.

“Someone recently tried to use an application to sign in to your Google Account,” says in the email. “We prevented the sign-in attempt in case this was a hijacker trying to access your account. Please review the details of the sign-in attempt in attached file.”

The attached file is deceptively named Google_Accounts_Alert-6284-S44-8098.zip, and actually contains an executable file – a backdoor Trojan that opens the way for other malware to be delivered to the victim’s machine, and is currently detected by only half of the AV solutions used by VirusTotal.
