    hi, iam using kvm with virtmanager since a while without problems (and also virtualbox) but now when i start a virtual manchine the host system reboots (virtualbox still run without problems), i dont know how to fix it. My system is an amd phenom x6 1100T, 16gb of ram (amd 1600 cas9), 1 tb wd blach edition sata3, amd HD5650 1gb ddr3, an the SO is ubuntu 12.04 64 bits.
    I have to say that boot with the ubuntu 12.04 64bits live-dvd, install kvm, and try to use one of the virtual manchines and the system reboot like with my installed system, 2 weeks ago i have no problems, maybe its a hardware problem, but virtualbox and all the others programs runs ok, the only that have problems is kvm. I test the mem with memtest and in 10 passed have no erros.
    i will waiting for yours response.
    thanks and sorry abouy my english.
    bye

    Any idea? i still will the same problem, the only that i can add is that 1 week ago after a huge update, i try again and works, i can virtualize windows 7 and centos, i was used for 2 hours, then shutdown the centos vm ok, and when i shutdowning the windows 7 vm the system restart, and after this restart all came back to the same, i can again use kvm becauso i press play to a vm the system restart. Well i look for info but i dont find nothing similar to my problem, and maybe i think thatcan be a problem of conpatibitity of the chipset mobo (990FX) and kvm, i dont know actually.
    thnks

    Solved -- The problem was the cpu, with a fx8150 works ok, but the old cpu its fine, because on a 870 mobo works ok with kvm, i think thats was an incompatibility of the mobo and the cpu.
    bye
