Hello all, I know that the question: Is it possible to run quemu inside Xen domU or run Xen domain 0 on quemu have discussed earlier in this mail list. As far as I remember this is possible except such a configuration where kquemu acceleration is in use. But what about HVM-capable systems? Please tell me are there the same restrictions for the hvm-capable...

Hi, I am not using quemu, i am using XEN, is there any option to allow me to do that? In the libvirt documentation specify that those options are only available on quemu.

Hi, Xorcom astribanks get initialized straight on when using Ubuntu 11.10 packages but I am having a hard time to get the same result running in a qemu/libvirt image. The first difficulty is that astribanks devices get different usb device ids during their initialisation process, requiring hot plug support. I have figured out how to solve this issue using the technique described in this post :

I've started writing it, but then I realized we might need third hook - in confirm phase - which would be run on the source when quemu switches control over to the destination, or when migration failed. And this is what I need to figure out, how to differentiate these two states on the hook script level. Michal

I''ve just posted my notes about installing Centos5 into domu on Solaris in http://vireso.blogspot.com Usually this thing requires installing Centos in quemu, then converting qemu image into xen image. But I think I''ve found much easier way. -- Sergey Ivanov.

Hi, I have a virtual machine defined by xml that start from pxe (network boot), my problem is that sometimes the dhcp server is not ready when the virtual machine try to boot. I need that the virtual machine keep asking for dhcp (network reboot) many times, until dhcp is ready and can start the virtual machine with a valid ip. How can I configure that in the xml file?

Chaps, Perhaps this question is a little basic for this list but I''m not really sure of the simplest method or best tool for the job. I''ve created some images with `dd=/dev/zero ....` and I''m using them for the domUs now. Some of them have been running for a few months with no probs. Trouble is that I''d like to create a separate partition within the domU.

Implementing a full-blown RDMA switch in qemu? RoCE rides over the existing ethernet switching layer quemu plugs into So if you built a shared memory, local host only, virtio-rdma then you'd probably run through the ethernet switch upon connection establishment to match the participating VMs. Jason

...eros. The found error cannot cause that block content is read from after the end of the block_seq image. The error does not spoil the C component and LBA 8444 is much more than a maximum cylinder size of 8 MiB away from the end of the 647 MiB image. If the H/C and S/H values were the same as with quemu's BIOS, then there would be no reason for the BIOS to refuse reading. (Does isohdpfx.bin any test for read error other than the magic number test of the read result ?) But with a different geometry it is possible that the S component of the wrong C/H/S becomes larger than the true S/H paramete...

...hrough kvm_mmu_notifier_invalidate_range_start). This is what ensure that KVM's dismatles its own mapping, it abides to mmu- notifier callbacks. If you did not you would have bugs (at least i expect so). Am i wrong here ? The mirroring kernel driver would also register the notifier against the quemu process and would also abide to notifier callbacks. What you want to maintain at all times is that none of the actors above ever look at different page for the same virtual address (ie one looking at older page while another look at new page). This is where you have helper like HMM that make sure...

Is there a way to determine what the hypervisor default NIC is? I'm using kvm/libvirt/qemu. If this is the wrong forum please please reply with that.

...me. It works perfectly on CentOS-6, CentOS-7, OpenSUSE-42.3, Fedora-29 (not tested later) and used to work on CentOS-8.0 Since CentOS-8.1 was released, IT chrashes with the following error: Plymouthd crash 913: ply_event_loop_watch_for_timeout: Assertion `seconds > 0.0' failed. I?m running quemu 5.0.0 with tianocore UEFI bios on MacOS (using accel=none or accel=hvf) (Bug also occurs with standard 256k bios) When I strace, I see multiple reasons but I can?t tell wich one is fatal. 1/ plymouthd reads /etc/Plymouth/plymouthd.conf (ok), then tries to read them from /var/run/plymouth/themes/&l...

That's right, I need also that second hook event. For your information, for now I manage locks manually or via Ansible. To make hook manage locks, I still need to find out a secure way to run LVM commands from a non-root account, but this is another problem.

Hi James Harper and others, I seen that problem already discussed early, but maybe it help you make hiding qemu devices when install gplpv driver. For now, when install gplpv i has not working qemu disk driver (gplpv works) and not working gplpv network (i think i can disable realtek network card and then gplpv will work). When you discuss German and French windows versions - you ask about
