Dear all, I install centos 6.3-64bit in a new server and also installed KVM using yum. Then I create a new virtual machine(i686) to install windows xp, but it's very slow, do you know why? Server: CPU: i7 3370, Memory: 16GB. Virtual machine: 1 cpu and 1GB ram. KVM information: qemu 4223 1 9 15:10 ? 00:00:41 /usr/libexec/qemu-kvm -S -M rhel6.3.0 -cpu SandyBridge,+osxsave,+tsc-deadline,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name xpt1 -uuid 36020e9b-d9b8-e831-7278-22adab258263 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/xpt1.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,driftfix=slew -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/libvirt/images/xpt1.img,if=none,id=drive-ide0-0-0,format=raw,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=22,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:f5:5f:6a,bus=pc i.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -device usb-tablet,id=input0 -vnc 127.0.0.1:2 -vga std -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 Thanks and best regards, Muiz _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
