Resource fragmentation. I'm quickly running out of disk space as I configure two guests to run on top of my host.Andy "Krazy" Glewhttps://www.blogger.com/profile/08442494949914217568noreply@blogger.comtag:blogger.com,1999:blog-2425290326823263574.post-89613555008100310392012-01-03T21:36:14.274-08:002012-01-03T21:36:14.274-08:00By the way, also started using Microsoft Virtual P...By the way, also started using Microsoft Virtual PC on the same laptop. <br /><br />Mainly to get Windows XP mode. Which is a Windows guest that I know I am licensed to. <br /><br />(Really, I want to install a Windows 7 guest. But I don't have install media and am unclear on licensing: can I use the same license both as host and guest on the same physical machine?)<br /><br />Would like to use Virtual PC and Virtual Box at the same time.<br /><br />... It seems that if I start up Virtual PC while Virtual Box is running, then Virtual Box gets a "Guru Meditation" critical error.<br /><br />I.e. it doesn't look as if I can run both of these different virtual machine managers at the same time.<br /><br />...<br /><br />Unsurprising, if they are competing for the same hardware VMX and VT-d support.<br /><br />TBD: if I disable hardware VMX acceleration, can they coexist?<br /><br />...<br /><br />People have often asked me why I am so much an advocate of user level virtual machines, as opposed to hypervisors. <br /><br />(Note: I want to say Type 1 (native, bare metal) versus Type 2 (hosted) hypervisors - but that's not quite right.<br /><br />well, here's an example: I have two nice bits of software, each convenient to a different VMM.<br /><br />Perhaps I can get Ubuntu to run under Virtual PC. Perhaps. But I have them both running in their respective VMMs *now*. <br /><br />It sucks that the VMMs fight. <br /><br />We have already shown that user level virtual machine managers can run. And, for that matter, coexist. Even while using the same hardware acceleration, aka VMX mode. Possibly not system level I/O acceleration, VT=d.. But VNX, nested page tables - that SHOULD be doable.Andy "Krazy" Glewhttps://www.blogger.com/profile/08442494949914217568noreply@blogger.comtag:blogger.com,1999:blog-2425290326823263574.post-41844332639837521062012-01-03T21:24:25.627-08:002012-01-03T21:24:25.627-08:00VB Seamless Windows mode only works on the primary...VB Seamless Windows mode only works on the primary Windows display.
