Find the detailed XenServer tools version

 

To get the UUID:

xe vm-list | \
awk '{if ( $0 ~ /uuid/) {uuid=$5} if ($0 ~ /name-label/) \
{$1=$2=$3="";vmname=$0; printf "%s - %s\n", vmname, uuid}}'

Then:

xe vm-param-get uuid=<uuid from above> param-name=PV-drivers-version

 

Example output:

major: 6; minor: 2; micro: 0; build: 6

major: 6; minor: 2; micro: 0; build: 7 (update http://support.citrix.com/article/CTX142219)

Browser Market Share Changing Over Time

 

Firstly I don't run an analytics company but I found one on the web (www.netmarketshare.com) and as a part of planning which browsers should be tested for a terminal services project I wanted to know the winners, losers and where IE6 still is.

Below are the last twelve months of browser change. Overall I will be testing on IE10. The others will all be tier 2 for business.

The big winners here are IE10 and losing out are IE8 and IE9. IE7 is still in slow decline, but what scares me is IE6 is static at 6% (Siebel use ActiveX controls). The total of IE releases is around 54%

Chrome with auto update is always the current release about 12% and the others falling away to a total 17%

Firefox is much the same around the 14% mark

Safari, Opera, Sleipnir, Maxthon, Comodo are ALL in the other 18% – here, have one www.browserchoice.eu/BrowserChoice/browserchoice_en.htm

XenCenter not showing performance stats?

 

I have four new XenServers (old v5.6 due to testing, but anyway). One of the four showed performance stats and the other three did now. After looking around the problem was all four had different time settings (specifically odd dates that were years out) and of course no NTP Setup.

To check this open the server console and use the ‘date’ command.

To fix this do the following:

1. Set manually the date/time. on the XenServer console use: date –s “14 AUG 2013 08:27:00”
2. Check to make sure your NTP is running and accessible: ping NTP.server.IP.Address
1. ‘vi /etc/ntp.conf’
2. Add NTP servers at the end of the file in the following format:
   server ntp.server.dns.domainname
3. Restart the NTP service: ‘/etc/init.d/ntpd restart’
3. Check your server ntpd process: ps –ef | grep ntpd
4. Make sure that your AD DCs and your XenServers are using the same NTP Server (optional)
5. Restart XenCenter and BAM!

If your uptime stats are wrong you need to reboot the affected XenServers.
