[Qemu-devel] [Bug 1739378] Re: qemu git master snapshot doesn't work

** Description changed:

  I'm having different issues trying to have QEMU snapshots working using
  qemu-system-arm with vexpress-a15 board.
  
  In this opportunity, I'm trying the git master head version:
  # git rev-parse HEAD
  af352675efb7e92a1f5f6461a042a12015ab3d12
  
- $ /usr/local/bin/qemu-system-arm -kernel kernel/vmlinuz-4.10.0-42-generic 
-initrd kernel/initrd.img-4.10.0-42-generic -M vexpress-a15 -m 2048 -append 
'root=/dev/mmcblk0 rootwait console=tty0' -sd vexpress-4G.qcow2 -dtb 
device-tree/vexpress-v2p-ca15-tc1.dtb  
+ $ /usr/local/bin/qemu-system-arm -kernel kernel/vmlinuz-4.10.0-42-generic 
-initrd kernel/initrd.img-4.10.0-42-generic -M vexpress-a15 -m 2048 -append 
'root=/dev/mmcblk0 rootwait console=tty0' -sd vexpress-4G.qcow2 -dtb 
device-tree/vexpress-v2p-ca15-tc1.dtb
  audio: Could not init `oss' audio driver
  
  Later on, when the machine finishes booting I savevm ss and quit.
  However, when I try to restore it, I have that Missing section footer
  error:
  
  $ /usr/local/bin/qemu-system-arm -kernel kernel/vmlinuz-4.10.0-42-generic 
-initrd kernel/initrd.img-4.10.0-42-generic -M vexpress-a15 -m 2048 -append 
'root=/dev/mmcblk0 rootwait console=tty0' -sd vexpress-4G.qcow2 -dtb 
device-tree/vexpress-v2p-ca15-tc1.dtb  -loadvm ss
  audio: Could not init `oss' audio driver
  qemu-system-arm: Missing section footer for sd-card
  qemu-system-arm: Error -22 while loading VM state

  OS: Ubuntu 16.04.3 LTS (xenial)
  
  $ gcc --version
  gcc (Ubuntu 5.4.0-6ubuntu1~16.04.5) 5.4.0 20160609

+ # git clone git://git.qemu.org/qemu.git
+ # cd qemu
+ # git submodule update --init --checkout
+ # make clean && ./configure --target-list=arm-softmmu && make -j8
+ # sudo make install
  
  I've also tried a different ./configure line, explicitly enabling some
  of the features, i.e. smartcard, with the same results:
  
  ./configure '--disable-user' '--enable-system' '--enable-linux-user'
  '--enable-modules' '--enable-linux-aio' '--audio-drv-list=pa' '--enable-
  attr' '--enable-brlapi' '--enable-virtfs' '--enable-cap-ng' '--enable-
  curl' '--enable-fdt' '--enable-gnutls' '--disable-gtk' '--disable-vte'
  '--enable-libiscsi' '--enable-curses' '--enable-smartcard' '--enable-
  rbd' '--enable-vnc-sasl' '--enable-seccomp' '--enable-spice' '--enable-
  libusb' '--enable-usb-redir' '--enable-xfsctl' '--enable-vnc' '--enable-
  vnc-jpeg' '--enable-vnc-png' '--enable-kvm' '--enable-vhost-net'
  
- How have I built it?
- # git clone git://git.qemu.org/qemu.git
- # cd qemu
- # git submodule update --init --checkout
- # make clean && ./configure --target-list=arm-softmmu && make -j8

  As a reference, and just in case these may be in some way related, I've
  just submitted another ticket for a different issue with snapshots using
  Ubuntu Qemu version (https://bugs.launchpad.net/qemu/+bug/1739371)
