similar to: hvm in xen via libvirt.

hi, i am trying to create hvm in xen via libvirt but i am facing some error. i installed the packages like bltap-utils, blktap-dkms in my dom0. virsh create tiny_core.xml p11-kit: invalid config filename, will be ignored in the future: /etc/pkcs11/modules/gnome-keyring-module error: Failed to create domain from tiny_core.xml error: internal error: libxenlight failed to create new domain

Hi friend. I have a problem about using libvirt now. There is a feather about HVM driver ---PV_on_HVM_drivers, in xm configure, using flag xen_platform_pci can control the feather, but in libvirt I can not find the flags to use pv-on-HVM drivers. So I want to find the answer if the libvirt can control the modules using xml file? thanks a lot. best regards. zhong.chunshan

Hi, I seem to have an interesting issue with vif-route. This is after an update to Xen 4.2.1, switching from xm to xl. I have 10 PV domUs on the host and two FreeBSD ones. All the PV domUs are now working nicely. Since FreeBSD has always been just slightly broken as PV I chose a HVM domU for those, but with PV drivers. Those PV drivers all blew up now after the upgrade. I''m now trying

All modern kernels are PV compatible. You can take the same Linux image and run it HVM or PV.

Hi All, I sent the patch to allow blktap to be able to booted as system bolume for PV-on-HVM. However, there was a problem that hdN and xvdN were not able to be specified at the same time. I made the patch to correct it as follows. - Whether hdN is defined first is checked. - If hdN is defined, xvdN is not replaced with hdN.

I''ve been trying to compare memory access speed between bare-metal, xen-pv and xen-pvhvm (hvm with pv drivers). In all 3 setups I''m running the same kernel (3.6.6), built with support for xen, on a 64 core AMD Opteron 6378. The output of xm info (relevant parts): machine : x86_64 nr_cpus : 64 nr_nodes : 8 cores_per_socket : 16

Hi, I am trying to setup Xen to use "PV on HVM". For this, I did the following. (1) I followed the tutorial at http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial to setup Xen4.0.1 on Fedora13. I am able to run virt-manager and create a Fedora 13 guest. (2) I followed the tutorial at http://bderzhavets.wordpress.com/2010/05/27/pv-on-hvm-at-xen-4-0-on-top-of-fedora-13/to use PV on

Thanks for the reply. Sorry for the typo in the earlier mail. I have PV-HVM of CentOS 7 & I need to convert it to PV kernel. Basically here I am trying to see whether my PV_HVM kernel is vulenrable to this issue given in the following link http://seclists.org/oss-sec/2015/q3/212 In the above link, it was mentioned that the PV kernel is not vulnerable to this bug, but HVM is. It didnt say

Greetings, I would like to know how one can identify if a DomU is PV or HVM? Any docs which may indicate a way to find out? I have a CentOS 5.5 64bit DomU which might be HVM - how can this DomU can be made PV? Just stop the DomU, and then delete it using Virtual Machine Manager and the create another config file for a PV DomU and use xm new and then xm start? Let''s say I have a config

Hi Jeremy, I backported the branch I have in linux-next plus some older PV on HVM fixes to stable-2.6.32.x.

Thanks for the reply. If we want to have PV kernel for CentOs 7 , are there any guidelines to follow? How we can know before hand itself that this kernel is PV or HVM, without installing kernel?

Hi I run some hibernation tests on windows HVM and HVM with windows pv driver. The test case is common scenario test(one test case of WHQL test), this test case will hibernate the vm for many times, and doing some IO operations for devices. The windows guest is Srv2008 R2 x64. Following is my test result HVM guest with pv driver, machines 1cpu and 2cpu 4cpu AMD pass pass Intel pass

Hi All, I sent the patch to make blktap work with PV-on-HVM. I corrected the part that had been pointed out in the Xen community. ・All xvdN disk is looked like hdN. ・All tap disks are checked.(tap:aio, tap:sync, tap:vmdk, etc.) We cannot use blktap for the volume of the system with PV-on-HVM and are embarrassed. Could you apply this patch? Or, please give the comment to me. Signed-off-by:

Dear all, In case of someone else is trying to do the same configuration as mine, I stated below the steps to configure HVM and PV''s domains to use FIXED VNC Ports (instead of having Xen automatically assign one unused port based on domain id): For HVM''s: vnc=1 # Enable VNC vncconsole=0 # Don''t start vncviewer after "create" the

HVM = fully virtualized. The question is, why are you using fully virtualized domUs?

Hello all, I have a question about the installation of a FreeBSD i386 PV DomU. Is it possible to install a FreeBSD i386 PV DomU directly from Dom0 without the need of a HVM DomU? So my Dom0 is Debian Squeeze running on Xen 4.2. I found no information about this in the web. They all first create a HVM guest and convert it to PV which I think is a very uncomfortable way.
