I agree that latency sensitive work loads will probably run on bare metal for the time being. Work is being done in this area.

I also agree that the application load should be tested and only been put in the clouds if it makes sense.

Lets not compare mainframes vs x86 hardware. I was talking about heavy video streaming btw. You cant have any latency in network packets and IO because of virtualization. Moving everything to the “cloud” is not the solution for everything.

“For small projects its ok but not for what we do. “… Tell that to the mainframe users that has been running the worlds most high performance mission critical loads on virtual machines for a lot of years.

The hardware and software outside the mainframe world is only starting to catch up. The mainframes has about 30 years head start on this kind of tasks.

RHEL 6 will only support KVM. Migrating from XEN to KVM is as simple as booting in the regular kernel and booting your images from KVM. I run/test Xen,XenServer,KVM and I am going back to run physical servers + load balancers. I jumped on the virtualization bandwagon and its time for back to basics. For small projects its ok but not for what we do.

Yes, RHEL 5.x has yum and no up2date. RHEL <= v4.x got up2date.

RHEL have yum ? I have used RHEL long back, at the time, it was up2date and had problem with its licencing, then moved to centos.

Did someone already moved from XEN to KVM? I did not find a migration path from XEN (RHEL 5.3) to KVM (5.4) for paravirtualized VMs.

Is that possible to perform such an upgrade on a working web server? I mean I don’t have physical access to the server. Are there any things that might go wrong?

The upgrade option is the same as the update command with the –obsoletes flag set. Use update option.

Hi Vivek Gite,

I just checked
http://www.cyberciti.biz/tips/upgrading-centos-51-to-52.html

That URL shows a migration of CentOS from version 5.1 to 5.2 — and while that is not “true Red Hat”, CentOS is Red Hat minus the logos (Red Hat allows the CentOS community to have their distro provided they remove all Red Hat(tm) logos etc). Sorry if I’m being ‘master of the obvious’ here…

My real question here is – should one (whether they upgrade a Red Hat distro or CentOS distro use
yum update
and then
yum upgrade?

It seems that is what is at that URL – that one does the update then the upgrade.

Just curious

Thanks

@Jack,

The last link is for migration from RHEL to CentOS server.

Just wondering (see links below) – the info below infers one does the update then the upgrade with yum (again, see links below).
1) do the update with yum
2) Then ==> yum upgrade
http://www.cyberciti.biz/tips/upgrading-centos-51-to-52.html
or
http://help.godaddy.com/topic/90/article/5558?isc=tech57
While the URL above shows centos, centos is Red Hat without it’s logos.

So (just curious here) – is it perform an update and then upgrade?

Thanks

@Yonit,

It’s unknown if Red Hat will continue to support Xen with RHEL6. Xen is the past and KVM is the future as it is part of Linux kernel itself. However, they will NOT drop Xen immediately as tons of XEN servers are powered by RHEL 5.x. Also, Red hat support RHEL 5.x for 7 years.

Does that mean the Redhat is moving from Xen to KVM?
Xen will not be supported in RHEL 6 ?
