Hello, This is my first attempt on a kickstart installation. Would like to learn more about it and have read several tutorials. But I can't quite get it to work. What I've done, is to mount the centos iso that I've downloaded, copied the files to new a new directory that I called /root/kickstart_bui...

Interessting. --checksig and -K appears to be the same but not documented in man rpm. rpm -Kv gives me something like: rpm -Kv MQServer91Normal-1-0.x86_64.rpm MQServer91Normal-1-0.x86_64.rpm: Header SHA1 digest: OK (656836f8425944c544165cc75a09dfb9fc46b5e5) MD5 digest: OK (c8e6c9c3cc269242ab6e93dd7f...

Some additional settings appears to be required such as a...

Ok, this problem is sort of solved. The solution was to update the "Windows Server 2012 R2" driver. Since Hyper-V Core is basically the same as running Hyper-v on Windows Server 2012 the driver is compatible. Just for the record the driver can be found here : http://h20564.www2.hpe.com/hpsc/swd/publ...

I tried to install a fresh centos system on the hyper-v with the result that it now shows 10000Mb/s with the ethtool. I also updated one of the older systems to the latest release which now also show 10000Mb/s with the ethtool. But practically when transfering data I still only get 100Mb/s... :?: [g...

It's weekend and I have some time to try to get to the bottom of this problem. After googling some more I found the ethtool that I didn't know of until now. First thing is that the ethtool gives me an emtpy output on those systems that have a slow x11 connection over tcp. example : > ethtool eth0 Se...

Hello, I have an odd issue with x11 forwarding. I've been googling and searching in the forum for quite a bit but could not find any solution yet. In my home LAN I have one Mac book pro (VMWare) and one HP Proliant DL380 G8 (Hyper-V 2012 core). Both systems host Centos 7 VMs. When I forward x11 from...
