I tried setting xen_platform_pci=0 on my test ubuntu 11.10 livecd VM hoping it would run in HVM only mode, but the guest''s logs showed it detecting the Xen host and loaded the PV netfront driver (after modprobe). Is this expected behavior? Is there no way to force HVM only and not PVHVM or total PV? Setup: Xen Unstable...

Hi, Here is a little patch that attempt to fix the issue regarding xen_platform_pci=0 not been handled. There is one patch left from the previous version. The patch that was adding qemu_machine_override have been removed as it is unnecessary. If someone wants to change the -machine, it can always add it to device_model_args_hvm, as QEMU appear to use the last one. Regards, Anth...

...dule is unnecessary and it has been for a while. Most Xen systems will not be using the module, even now, because xen-detect is not installed by default on most Xen systems, and dracut uses xen-detect to decide whether to include the module. It also has some problems: 1) it does not try loading xen_platform_pci; 2) it loads modules unnecessarily; modules.alias is where all Xen support should reside. Assuming xenbus_probe_frontend and xen_platform_pci are loaded so that Xen devices are probed, other modules are picked up automatically thanks to aliases such as alias xen:vbd xen_blkfront 3) Even not...

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...

The user has the option of disabling the platform driver: 00:02.0 Unassigned class [ff80]: XenSource, Inc. Xen Platform Device (rev 01) which is used to unplug the emulated drivers (IDE, Realtek 8169, etc) and allow the PV drivers to take over. If the user wishes to disable that they can set: xen_platform_pci=0 (in the guest config file) or xen_emul_unplug=never (on the Linux command line) except it does not work properly. The PV drivers still try to load and since the Xen platform driver is not run - and it has not initialized the grant tables, most of the PV drivers stumble upon: input: Xen V...

...ppear from dom0.. so the bridge in dom0 doesn''t have any vifs/taps connected to it anymore. Has anyone seen that behaviour? I bet that''s also the reason why eth0 inside the PVHVM guest has a MAC address with only zeroes in it: 00:00:00:00:00:00. If I disable PVHVM with "xen_platform_pci=0" in the domain cfgfile then network for the guest works OK using the qemu-dm emulated nic.

The xen_platform_pci xl configuration parameter currently has no effect on upstream QEMU; creation of the platform device is hardcoded. I have created a patch to QEMU to remove this hardcoded creation. This patch specifies the appropriate -device argument on the QEMU command line (and hence creates the device) only whe...

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

...w to create an ISO.. that''s not quite the intention of these images. SolusVM intends for you to install the OS from an ISO which it will then manage. This is quite possible but I don''t know much about SolusVM. What you would need to do is: 1. Boot the VM in pure HVM mode (without xen_platform_pci enabled). 2. Install the guest operating system. 3. Apply the changes listed in the bottom of the README file here: http://mirror.orionvm.com.au/pub/ubuntu/1204/README 4. Reboot the VM into PVonHVM mode (xen_platform_pci=1) That is the rough outline though I don''t know how if SolusVM give...
