similar to: How to build PV driver with PV Dom0 for hvm?

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and

Hi list, I''ve read about recent efforts to push pv-on-hvm drivers to Linux mainline and I''m curious to know the cause for this. What''s the advantage over using pv_ops directly and booting the kernel paravirtualized? Are there plans to move Linux domUs closer to the KVM way (from an architectural point of view)? Hope you can help. Regards, Markus

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

Anyone had tried the save/restore against rhel6 guest? I found it always throw timeout when I tried to save the guest. And only fail with rhel6 guest.(ubuntu, fedora are ok). best regards yang _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi there guys. I''m using CentOS 5.4, I was able to compile my custom Dom0 kernel and boot it, now I''ve got some doubts. I''d like to compile a custom DomU image, the problem is that when I do, make kernels KERNELS="linux-2.6-xen0 linux-2.6-xenU" it tries to download the kernel from the HG repository which seems to have old 2.6.18 kernels, I want to use the GIT

I have been google for a few days now trying to get the Citrix PV Drivers to work on a server 2008 R2 HVM guest. I get the machine up and running then I install the cirtix PV drivers. I have tried both making and not making the registry change. Once I reboot the server I get stuck at the boot screen. The xen log says: XENUTIL: WARNING: CloseFrontend: timed out in

Hi, I''m the Mageia XEN packager and during QA, we stumbled into a problem. in fact, we wanted to test Mageia 3 installation on a HVM. so, we had a sparse image and a iso file: [ ''file:/opt/testhvm.img,sda,w'', ''file:/opt/mageialive.iso,hdb:cdrom,r'' ] the live booted, and was able to install to disk, but it never seemed to boot after the install...

Hi Keir The latest (hybrid) patchset again... Change from v5: Address the comments from Tim. Change from v4: 1. Add support for PV clocksource on HVM. (Replace evtchn enabling with pv clock enabling). 2. Update the patch following Tim''s comments. Change from v3: 1. Minor polish the patchset. Replace several specific is_hvm_pv_evtchn_domain() judgement. 2. Name changed...

I''ve just pushed some changes to hg that seem to speed things up a bit for me. On one machine with 2 x dual core 2.4Ghz AMD cpu''s, testing with iperf from DomU to Dom0 I get: Windows (vcpus = 2) - ~500MBits/sec - ~66% cpu utilization (eg 100% on one, and 33% on the second cpu) Linux (vcpus = 1) - ~2200MBits/sec On another machine with 1 x dual core 1.8Ghz AMD cpu, testing as

Hi, Im trying to install Netware and Windows 2008 server but im having problems with it reading the ISO. Im guessing this is because im running version 3.2.1 debian packages so i want to upgrade to unstable and use the 3.4 deb packages. My problem is that there isn''t a kernel package so when booting you cant boot into xenified kernel mode. If i try and use a kernel from the

Hello, I just wrote a step-by-step tutorial how to install the latest Xen 4.0.1 hypervisor on Fedora 13 (x86_64) host from src.rpm packages, and the pvops dom0 kernel from git repository. Check it out: http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial It also shows how to install various Xen PV guests using the native distro installers: - CentOS 5.5 - Fedora 13 - Ubuntu 10.04 LTS

I''m having issues with HVM live migration and every xen version I''ve tried - 3.0.1, 3.1.x, 3.3.0 and 3.3.1.

Hello, In http://wiki.xensource.com/xenwiki/Xen4.0 we mention the following: "Better performance and scalability: 128 vcpus per guest, 1 TB of RAM per host, 128 physical CPUs per host (as a default, can be compile-time increased to lots more)." But what''s the max supported amount of memory for a (64bit) guest? -- Pasi _______________________________________________

Hi, milos/list, now I''m working on some code related to page sharing. Are there any document/wiki that show how to setup the page sharing environment, so that I can test my code? Checking the code, I noticed the only tapdisk/blktap will use this page sharing mechanism. I''m not sure HVM guest without PV driver can use blktap, so does page sharing support HVM guest? Sorry that

I am not clear with the working of hypervisor xen. How does an instruction executed by kernel in Ring0 of DomU gets mapped or executed by hypervisor and then is excuted in Dom0. Is this thing some where on the wiki page? -- Tapas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, guys, I''m sorry to disturb you. I am a student. I want to use Xen to do some test about memory sharing between two domain. I am a newbie in Xen memory sharing. I want to set up a environment. I search on the internet. I find some patch for old version. However, I want to running on Xen 4.1 or 4.2 version. Does this still work? Can you help me? Can you give some instruction on this?
