Hello, To explore kvm installs via Virt-Manager, I tried win7 installs in 3 different hosts. All 3 have 2G of RAM or more. Windows 7 Ultimate in 2.5 GB DVD ISO 1) Centos 5.4, AMD am2, Athlon 64 x2 4600+ works 2nd attempt after setup of Br0 (bridged network) virt-manager-0.6.1-8.el5 kvm-83-105.el5_4.13 2) OpenSuSE 11.2, AMD am2, Athlon 64 x2 5200+ works with defaults (Br0 is setup on OS install) virt-manager 0.8.0-5 kvm-0.11.0-4.5 3) Centos 5.4, Intel LGA 775 C2D, E7600 3.0 Ghz fails in shelled kvm and Virt-Manager with Br0 the Intel C2D box works so well - cooler and faster then the other two - but somehow the kvm intel support seems flawed. The win7 install gets past 2 boots and issues a VM exception in vcpu0 right after the third boot. Maybe someone else succeeded with a similar Intel setup. -- Mark /etc/libvirt/qemu/ ------------- win7kvm.xml ------------- <domain type='kvm'> <name>win7kvm</name> <uuid>d9113860-4731-4622-bc2e-54b656e1567a</uuid> <memory>1048576</memory> <currentMemory>1048576</currentMemory> <vcpu>2</vcpu> <os> <type arch='i686' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> </features> <clock offset='localtime'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu'/> <source file='/data2/kvm/win7.img'/> <target dev='hda' bus='ide'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu'/> <source file='/data2/kvm/WIN7_Ultimate_EN_DVD.iso'/> <target dev='hdc' bus='ide'/> <readonly/> </disk> <interface type='bridge'> <mac address='54:52:00:36:a2:59'/> <source bridge='br0'/> <model type='rtl8139'/> </interface> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> ----------- unsnip -----------------
