hi I try to understand the code of xen memory there are gmfn, gpfn and pfn in the xen and in the /xen/include/xen/mm.h there are some explanation about them as follows: * 1. gpfn/gpaddr: A guest-specific pseudo-physical frame number or address. * 2. gmfn/gmaddr: A machine address from the p.o.v. of a particular guest. * 3. mfn/maddr: A real machine frame number or address. * 4.

Hi! What benefits do I get if I put "type=paravirtualised" in my network card config for a Win2k8 domU with PV drivers installed? Is it necessary, will it improve performance? I have read about this option here: http://plone.lucidsolutions.co.nz/linux/xen/windows/windows-server-2008-r2-xen-hvm-installation-with-gpvpv-drivers Thanks, Daniel

Please tell me any link which I can follow to convert the Ubuntu 10.04 64 bit Desktop as paravirtual guest. I have tested it . But after conversion it comes to text mode. * * _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Yesterday, I had a PV OpenSolaris DomU stop responding. I looked on my xen machine and it was in a paused state. I ended up destroying it and then doing xm create to bring it back up. It won''t boot, and I think PyGrub is hanging. Not sure how to resolve this, there aren''t any errors being presented in xen/xm itself. If I try ''xm create config.conf'' it just

(The list appears to have eaten my previous attempt to send this. Apologies if you receive multiple copies.) The attached patches allow you to use paravirtualised network and block interfaces from fully virtualised domains, based on Intel''s patches from a few months ago. These are significantly faster than the equivalent ioemu devices, sometimes by more than an order of magnitude.

Hi. I has xen virtual machine in paravirtualisation. Host and guest sysstems are CentOS. When I use top in guest machine I see, that system use 20% resourses. But in host machine I see, that machine use 50% resourses. In config machine has 5 processors, and has cpu_cap 352. Processor is 2266MHz. Therefor for statistic in guest machine it use ~ 2266...

Hi, I''ve seen this asked a few times, but I just can''t work out whether I am misinterpreting how this is supposed to work, or if it is just broken in my setup. What I want is to be able to see the character cell console of DomU''s via VNC. As far as I understand, when I create/startup the DomU, then a vnc server should start listening on my Dom0. I have tried every

Hello, I just installed Xen 4.0.1 on Ubuntu 10.04 dom0. After this i had Ubuntu 11.04 as Para domU. I tried to attach file based disk to the this domU.

But inside the DomU i cannot see any disk xvdb. xend.log shows : [2011-10-25 16:27:32 14794] DEBUG

Hi, i''m prepering to upgrade my servers from xen 3.0.3 32-bit to 3.2.1 64-bit. The old system: Debian 4.0 i386 with included hypervisor 3.0.3 (pae) and dom0 kernel. The new systen: Debian lenny amd64 with the included hypervisor 3.2.1 and dom0 kernel from Debian 4.0 amd64. My domUs have a self compiled kernel out of the dom0 kernel of the old system (mainly the dom0 kernel but

Is there any way to make gaming in domU work? It''s not clear to me, if this can be done with open-gl or so. If this is impossible now, is some development planned in this area? Eventually I would wait buying my next pc until the necessary cpu features are available. TIA, martin -- _______________________________________________________________________________ No MS-Word attachments

Hi all, I was wondering if cpu frequency scaling in dom0 (using the cpufreq=dom0-kernel boot parameter) may cause problems with HVM domUs? This is on Xen 3.2.1. PV domUs seem to work just fine. They adjust to the frequency change on the go. The HVM I run using the unmodified_driver drivers (also from the 3.2.1 release) seem to have very slow timers if dom0 lowers the frequency. Birger
