Hi,all,i build qemu-kvm1.0.93 from source code on centos6.2 , # qemu-system-x86_64 --version QEMU emulator version 1.0.93 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard and the guestfish's version: # guestfish --version guestfish 1.7.17 but when i use the guestfish command to upload a file to a vm,it does not work , # guestfish --rw -i -d centosvm upload /test/ifcfg-eth0_centos /etc/sysconfig/network-scripts/ifcfg-eth0 the command doesnot return any error massage and keep running till i press crtl+c.

i build qemu-kvm like bellow: ./configure --target-list=x86_64-softmmu \ --prefix=/usr/local/qemu-kvm \ --sysconfdir=/etc \ --audio-drv-list=alsa \ --audio-card-list=ac97,es1370 \ --disable-strip \ --disable-xen \ --enable-virtfs \ --block-drv-whitelist=qcow2,raw,file,host_device,host_cdrom,qed \ --disable-debug-tcg \ --disable-sparse \ --enable-werror \ --disable-sdl \ --disable-curses \ --disable-curl \ --enable-vnc \ --enable-vnc-tls \ --enable-vnc-sasl \ --disable-brlapi \ --disable-bluez \ --disable-docs \ --disable-vde \ --enable-linux-aio \ --enable-kvm \ --enable-spice \ --enable-kvm-device-assignment \ --enable-trace-backend=dtrace \ --enable-smartcard \ --disable-smartcard-nss \ --disable-guest-agent could anyone give some help?thanks. _______________________________________________ Libguestfs mailing list Libguestfs(a)redhat.com https://www.redhat.com/mailman/listinfo/libguestfs

libguestfs 1.7.17 was what we supplied in RHEL 6.1 / 6.2 and CentOS derivatives, but it's rather old and cannot cope with anything except the qemu which is also supplied in RHEL. I'd suggest first of all trying the RHEL 6.3 packages here:  http://people.redhat.com/~rjones/libguestfs-RHEL-6.3-preview/

Secondly, use the regular qemu and kernel packages supplied by Red Hat.  These contain all the bits needed for libguestfs to work, and have been extensively tested.

qemu-kvm-1.1-rc4 does not support guestfish 1.16.19 too....

libguestfs is from you:http://people.redhat.com/~rjones/libguestfs-RHEL-6.3-preview/

qemu-kvm from your company didnot support blkdev_snapshot ,so i build must build it from source by myself,

guestfs_get_qemu: /usr/libexec/qemu-kvm
