[PATCH v3] virtio-balloon: optimize the virtio-balloon on the ARM platform

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

[PATCH] virtio-balloon: optimize the virtio-balloon on the ARM platform.

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 u

Optimization for the virtio-balloon feature on the ARM platform

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

VM crashed while hot-plugging memory

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

[PATCH] net: Fix qemu crash when hot-pluging a vhost-net failed.

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: vhost backend
