Talk:X86 virtualization
From Wikipedia, the free encyclopedia
Maybe I don't understand the topic, but weren't there x86 virtalization products long before VMWare? VirtualPC and SoftWindows95 come to mind. Anirvan 23:46, 19 Apr 2005 (UTC)
- The article is specifically addressing the case of virtual machine monitors for carving up an x86 machine into multiple virtual x86 machines. This is not as easy a task as one might imagine, which is why some pretty nifty technology is required. Mark Williamson 18:14, 20 Apr 2005 (UTC)

[edit] Merge
Perhaps this article and Virtualization Technology should be merged? They both try to discuss hardware and software virtualization on the x86 architecture. -- Bovineone 18:51, 15 February 2006 (UTC)
=>Mabye, mabye not, first they should both be cleaned up. Second, they should be seperated and cleaned so that Virtualization Technology should contain implemented hardware (with accompying software) techniques, where X86 virtualization should discuss generic techniques involved (ring 0 and the like). But I agree, at the mement they are both very similar. --220.237.182.188 10:21, 20 February 2006 (UTC)
I agree that they should not be merged. Virtualization Technology is about a very specific hardware feature, while X86 virtualization is about virtualization on x86 processors in general. Surely the latter should link to the former, but including the former in the latter would be putting too much specific information in a general article. ThinkingInBinary 22:06, 7 April 2006 (UTC)
I think they probably should be merged, since both are quite short, and the data in Virtualization Technology is highly relevant for the future of virtualization on x86. However, if they're not, then at least the name of the Virtualization Technology article needs to be changed. It's an incredibly general name, sounding far more general than the name of the X86 virtualization article, while in fact being much more specific. It should properly be named something like AMD and Intel hardware features for virtualization (horrible name) or some such. JZ 17:52, 12 April 2006 (UTC)
How about Hardware X86 Virtualisation? RealLink 11:48, 14 April 2006 (UTC)
Surely the other way round, Virtualization Technology can cover ALL types of Virtualization, where as X86 Virtualization can only cover a subsection.... --NigelJ talk 02:44, 30 April 2006 (UTC)
- The phrase "Virtualization Technology" in that capitalization refers specifically to the name being used by Intel and AMD for the hardware-assisted virtualization features, not something more general than that. -- Bovineone 06:47, 18 June 2006 (UTC)
There doesn't seem to be enough non-x86 information here to justify separate pages. Even including a little information about IBM and HP virtualization won't really do it. The pages can always be separated later when sufficient material is available. Also, the information under the Use heading on the Xen page looks like it would fit well here.

- Agreed, since both articles were relatively short and overlapped in some areas content, I've just merged them. -- Bovineone 06:47, 18 June 2006 (UTC)
[edit] Cite sources tag?
Under "Software utilizing VT," and "The following software is known to conditionally make use of virtualization technology features:" Microsoft Virtual PC has a "citation needed" tag... doesn't the link cite itself? Maybe I'm not quite getting what the list is specifically speaking of, but isn't the added html comment "since what version?" is answered by the link as well... right? Again, I might just be missing what the list is specifying. -- KyleP 00:39, 14 October 2006 (UTC)
[edit] x86 virtualization is the method by which the x86 processor architecture is virtualized
Recursive definitions are uninformative, in general. Can someone come up with a definition which is actually helpful? I admit to being at a loss for one at the moment. --Scott McNay 00:54, 6 November 2006 (UTC)
[edit] Popek/Goldberg, x86 virtualization and the tone of the opening pp
I disagree with the spirit of the opening statement. Popek and Goldberg guidelines are, as openly stated within their paper, only general and not a list of "necessities". Virtualization on the x86 platform evolved quite nicely over the years well before the advent of AMD-V and Intel-VT. Even now, the leading virtualization technologies are only beginning to take advantage of the very early hardware support that the AMD and Intel extensions are adding. It is not until the next wave of hardware support that virtualizes I/O, and the next wave of virtualization products that are optimized to take advantage of hardware extensions fully and capitalize on the advances of Intel-VT-d and AMD-V+1, that we will really understand the implications of hardware supported virtualization on the x86 platform. Despite that, there are many real-world production case studies of VMWare and Virtual Server being utilized on a large-scale today. The article implies that Popek-Goldberg somehow establishes a gospel for what is absolutely mandatory to have successful virtualization and that, it is only now, that the x86 platform has "met the requirements" that it can be done "easily". That is all a dramatic oversimplification. —The preceding unsigned comment was added by Mlambert890 (talk • contribs) 06:35, 8 January 2007 (UTC).
[edit] is the virtualization detectable from the guest?
Can a guest detecht if it is running as a guest within a hypervisored environment? If not it should be possible that it starts its own hypervisor and the virtualization can be nested endlessly, right? --84.72.190.27 13:22, 26 March 2007 (UTC) (de:Benutzer:RokerHRO)
