This can be observed in qemu monitor too, info qtree: dev: ivshmem, id "" chardev = "" size = "2048M" vectors = 1 (0x1) ioeventfd = false msi = true shm = "foo" role = "" use64 = 1 (0x1) addr = 05.0 romfile = "" rombar = 1 (0x1) multifunction = false command_serr_enable = true class RAM controller, addr 00:05.0, pci id 1af4:1110 (sub 1af4:1100) bar 0: mem at 0x40000000 [0x400000ff] bar 2: mem at 0xffffffffffffffff [0x7ffffffe] Check dmesg, it fails to allocate for me, but with 1G it works (f22 x86_64). I don't know what's the reason behind it. Note that it's not safe to do hotplug with ivshmem (it may assert in various ways), I proposed a patch series a few weeks ago, I am going to send an updated version soon. -- Marc-André Lureau
