Re: [ilugd] Finding Virtualization Software that Fits
All, apologies, can't share the article till next month I believe. However, @Ashish, agreed Xen is much more forgiving when it comes to supported hardware, but you really cant compare Xen's performance on a server class system to its results on a desktop class machine. Also, last I checked, which was some time in Oct 2010, there were also restrictions on adding machines with heterogeneous CPUs to a server cluster (If this has changed, I would love to be updated). Finally, unless you're running a Xen modified kernel on your guest OS, you really dont get much mileage from it. Essentially I left Xen out on the same token that I left ESX out, i.e. designed for a different class of systems. On Thu, Sep 1, 2011 at 11:23 PM, Mahesh T. Pai paiva...@gmail.com wrote: Hmm...

However, @Ashish, agreed Xen is much more forgiving when it comes to supported hardware, but you really cant compare Xen's performance on a server class system to its results on a desktop class machine. With hexacore CPUs, fast memories, SSDs, NICs available for desktops, I guess the gap is getting narrower. And IIRC, the article is about desktop class hardware ;) Also, last I checked, which was some time in Oct 2010, there were also restrictions on adding machines with heterogeneous CPUs to a server cluster (If this has changed, I would love to be updated). Could you please explain, what you mean by that? Finally, unless you're running a Xen modified kernel on your guest OS, you really dont get much mileage from it. Essentially I left Xen out on the same token that I left ESX out, i.e. designed for a different class of systems. Not anymore. Thanks to paravirt_ops[1] kernel support which was present in Linux kernel since 2.6.23, you can use same kernel to boot as dom0, domU, or without Xen. I've never used VMware ESX (nor I intend to), but from what I heard it's more like a virtualization OS made to run on bare metal, unlike Xen which doesn't restrict you in this way, so you can use dom0 for different purpose.

You can run Xen on your X11 GUI enabled GNU/Linux box which you use daily for watching pr0n, hanging out on social networks, writing code, etc., and run VMs, and get better performance with VMs (paravirtualized). Not sure, why you think Xen is enterprise only. And also to read that article one needs to subscribe to the magazine, but they're mising the A tag around click here. As I see, you're the author of the article and hoping for some feedback, you can probably make it easily accessible i.e. without requiring LFY subscription as well, thought I'm not sure if that's allowed. /feedback - -- Ashish SHUKLA “The only difference between the saint and the sinner is that every saint has a past and every sinner has a future.” (Oscar Wilde) -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.17 (FreeBSD) iQIcBAEBCgAGBQJOXoNyAAoJEMdGz6nnT6SwFIEQAJ+hx2s2wWGD64MoyWtfqbpA JykUqfllYLbGR47DXr3hrLNXtUQJQdkmh9SMtWWY4BFF2QtbxEBB33XRsnEpp3OZ IpioEBg8XgRrLyHXlQ+ZnvvBa4KVAkCHrefZ7Nts1jsLgsj7CqWIB15OO8M1/vQT NrtujXk9hfCmvg/fGFloTxydEAk051QLS0EVY0u6KcA/iiQaAOrvrRcOzTXIa3yM z6TI/WQaBabQCaQOLxytPxd21Savmd/I89R+Kth8qcvoBESDhL3lXBaNjEjfB8HE G27XTnFnXgTg//MDFppL5hwqKfTMs4GbhALJNVHjVozMJReyizTTx/gbqTHIW6qp FD16F0SAEOl+u67Q+xekiEgApb3TCRtzyRytZRwW/WbT+87ZvZw73rZTnQI1Okmp OnfVMWWWVj4fueLG8j77i22T1huFb1qfPhR8S6gbn8y84K8Z/jSIOfB+ViW1Hkab PoIR4+LWVTFY9Bll2trTgsR8tc9BRpoUNvYeYY1rJo7IRuf8u5027Ln+DJgD7G4f ytAni2fPOmiQ7szaHFq8q2D+mKRYzCIgzoyMhxgN5uEaXDMaMSHXCCtb2H/t05Gq MZbz8fhJC29XgW7qJUArOuHs5g4fUdRfqqg6G6bTuuZ3c+8L3P2S81Gq1vIL0Asa +G/aFSHVhmDa1Hpw7w59 =Bbo3 -END PGP SIGNATURE- ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd
