Hi, I'm running libvert on a Debian 7 system. I have upgraded libvert and qemu from source (v1.06 and 1.5.0 respectively) and the problem persists. The guest OS is also a Debian 7 system running a non-SMP kernel. The error message from virt-manager is Error starting domain: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: rtm,

Hi , Created new thread . Environment: Bare Metal server + CentOs with qemu/KVM +libvirt for virtualization Guest Instantiated with virt-install with forced CPU model like below virt-install --virt-type kvm --name compute-0 --cpu Haswell,+fma,+movbe,+fsgsbase,+bmi1,+hle,+avx2,+smep,+bmi2,+erms,+invpcid,+rtm --ram=61440 --vcpus=20 --os-type=linux --os-variant=generic After guest installation

Running a 3.14.4 x86-64 SMP guest kernel on qemu-2.0, with kvm enabled and -cpu host on a 3.14.4 AMD Opteron host, I'm seeing a reliable kernel panic from the guest shortly after boot. I think is happening in kvm_unlock_kick() in the paravirt_ops code: divide error: 0000 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 3.14.4-guest #16 Hardware name: QEMU

Hi On a range of Dell servers containing Intel 64bit processors, 'virsh capabilities' reports the cpu differently on Debian Wheezy-amd64 and Wheezy-i386. The results given by the Wheezy-i386 version seem very wrong (since n270 is an Atom processor). Apart from architecture, the package versions of libvirt-bin are identical: 1.2.1-1~bpo70+1. /usr/share/libvirt/cpu_map.xml files are

Hello everybody, First a big thanks for tinc-vpn I am still using it next to wireguard and openvpn. I am having a setup where the tinc debian appliance is at 100% cpu load doing about 7.5MB/s. Compression = 9 PMTU = 1400 PMTUDiscovery = yes Cipher = aes-128-cbc How can I pick a cipher that is the fasted for my CPU and don't create a CPU bottleneck at 100%. Kind regards, Jelle de Jong

hi, yes we are talking about same host here. You could've just used -cpu host-model-only >> I dont want to host model ( it is working with host model) . AS KVM seems to allow support Haswell with native commands . Does this mean in my case KVM is allowing software emulated cpu model. Can libvirt allow software-emulated for non host model ? if yes how . thanks On Tue, Jan 24,

Hi we observed that below errors occur on AMD platform since 25de7691a0e27c29c8d783a22373cc265571f5e9 root at lkp-opteron1 /opt/rootfs/llvm_project/src/build# cmake -DCMAKE_BUILD_TYPE=release -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm -DCMAKE_INSTALL_PREFIX=/opt/cross/ -- clang project is enabled -- clang-tools-extra project is disabled -- compiler-rt project is disabled

LKP framework can guarantee that all the software environment are same on AMD and INTEL platform. INTEL platform always work well, after revert this patch, AMD works well. we tried below commit on AMD. 1) 25de7691a0e27c29c8d783a22373cc265571f5e9: bad 2) a82235843b102202766115e10003c9465a8b83ae: good the error logs(build/CMakeFiles/CMakeError.log) has no difference b/w 1) and 2) on AMD platform
