Don't know about the kernel bug, but in (very very) recent versions of libguestfs it is now possible to force TCG by doing: export LIBGUESTFS_BACKEND_SETTINGS=force_tcg which should work around this bug. See: http://libguestfs.org/guestfs.3.html#backend-settings https://github.com/libguestfs/libguestfs/commit/26f7fb237b713c798e23a336a3c4973513f83551 https://github.com/libguestfs/libguestfs/commit/11ac9f702440fff5c8dad1f9756f24ca6867712c Rich. -...

Hey, I am getting this error after using virt-v2v-copy-to-local and trying to run: $ virt-v2v -i libvirtxml rhel7.xml -o local -os /var/tmp -of raw I try to set: export LIBGUESTFS_BACKEND_SETTINGS=virbr0=ovirtmgmt with no success and the file /etc/qemu/bridge.conf contains: allow virbr0 it only worked after creating the bridge, is there other way to import without creating the bridge? Thank you, Shahar Havivi

The man page for libguestfs says: export LIBGUESTFS_BACKEND_SETTINGS=force_tcg will force the direct and libvirt backends to use TCG (software emulation) instead of KVM (hardware accelerated virtualization). However, our application has many services (run by different users) which make use of libguestfs tools, and it is painful to have to set this environment...

Thanks. Reading the defect and the associated thread in https://bugs.launchpad.net/qemu/+bug/1661386, I enabled performance counters in VMWare guest settings. Now the kvm assertion `ret == cpu->kvm_msr_buf->nmsrs' is gone. But the qemu/kvm hangs after printing "SeaBIOS (version 1.10.2-1)" I presume this too is a qemu/kvm issue for vmware platforms. Is there any existing issue

Hello, I am running into problems with virt-builder on my Ubuntu-14.04 install. Please find the checklist below: 1. What are you trying to achieve? I'm trying to build a standard Ubuntu 14.04 disk image. 2. What exact commands did you run? I ran "virt-builder ubuntu-14.04" 3. What was the precise error/output of these commands? The process gets stuck indefinitely at

Let's actually compile and test the patch this time, rather than trusting the RHEL 7.6 patch to apply directly to head ... Rich.

v3: - Various changes to dhclient/dhcpcd as discussed on the mailing list.

v2: - Make virbr0 configurable. - Fix the tests.

This avoids the need to call out to external programs like qemu-img(1). guestfs_get_backend_settings guestfs_set_backend_settings Per-backend settings (can also be set via the environment variable LIBGUESTFS_BACKEND_SETTINGS). The main use for this is forcing TCG mode in the qemu-based backends, for example: export LIBGUESTFS_BACKEND=direct export LIBGUESTFS_BACKEND_SETTINGS=force_tcg guestfs_part_get_name Get the label or name of a partition (for GPT disk images).

Hi, I am having issues with libguestfs; I am unable to mount a disk either from cli or via python bindings. This was working previously, but in order to have access to python3.5 I am trying to upgrade from Debian 8/Jessie to Debian 9/Stretch. Unfortunately the libguestfs error is getting in the way. Output of libguestfs-test-tool is attached as per libguestfs.org help. My current environment:
