Re: [PATCH v2 00/10] virtio-mem: paravirtualized memory

[Pankaj Gupta]

Hi David,

Trying to test the series with the Qemu branch(virtio-mem) mentioned.
Unfortunately,
not able to hotplug memory. Is anything changed from your previous posting
or I am doing something wrong?

After giving value to "requested-size", I see size as zero.

(qemu) qom-set vm0 requested-size 10G
(qemu) info memory-devices
Memory device [virtio-mem]: "vm0"
  memaddr: 0x240000000
  node: 0
  requested-size: 10737418240
  size: 0
  max-size: 107374182400
  block-size: 2097152
  memdev: /objects/mem0

Guest kernel: 5.6.0-rc4
Using same Qemu commandline arguments mentioned in cover-letter.

Thanks,
Pankaj
