Dear all:
I found a bug of qemu: hot-pluging a vhost-net may cause virtual machine crash
in following steps:
1. Starting a vm without any net device.
2. Hot-pluging 70 memory devices.
3. Hot-pluging a vhost-net device.
After the 3rd step, the qemu crashed with following messages:

Optimize the virtio-balloon feature on the ARM platform by adding
a variable to keep track of the current hot-plugged pc-dimm size,
instead of traversing the virtual machine's memory modules to count
the current RAM size during the balloon inflation or deflation
process. This variable can be update
Dear QEMU maintainers,
I am writing to discuss a possible optimization for the virtio-balloon feature
on the ARM platform. The 'virtio_balloon_set_config' function is called
frequently during the balloon inflation process, and its subfunction
'get_current_ram_size' needs to traverse the virtual
Hello all:
I found VM crashed while hot-plugging memory.
Base infomation:
qemu version: qemu-master
requirements: hugepages, virtio-gpu
It happens by the following steps:
1. Booting a VM with hugepages and a virtio-gpu device.
2. Connecting VNC of the VM.
3. After the VM booted, hot-plugging 512

Optimize the virtio-balloon feature on the ARM platform by adding
a variable to keep track of the current hot-plugged pc-dimm size,
instead of traversing the virtual machine's memory modules to count
the current RAM size during the balloon inflation or deflation
process. This variable can be update
