Title:
nvme disk cannot be hotplugged after removal
Status in QEMU:
Invalid
Bug description:
Hello,
When I try to re-add an nvme disk shortly after removing it, I get an
error about duplicate ID.
See the following commands to reproduce. This happens consistently on
all VMs that I tested:
attach
==========
$VAR1 = {
'arguments' => {
'command-line' => 'drive_add auto "file=/dev/zvol/rpool/data/vm-20000-disk-1,if=none,id=drive-nvme1,format=raw,cache=none,aio=native,detect-zeroes=on"'
},
'execute' => 'human-monitor-command'
};
$VAR1 = {
'execute' => 'device_add',
'arguments' => {
'serial' => 'nvme1',
'drive' => 'drive-nvme1',
'driver' => 'nvme',
'id' => 'nvme1'
}
};
detach
===========
$VAR1 = {
'arguments' => {
'id' => 'nvme1'
},
'execute' => 'device_del'
};
$VAR1 = {
'execute' => 'human-monitor-command',
'arguments' => {
'command-line' => 'drive_del drive-nvme1'
}
};
reattach
===========
$VAR1 = {
'arguments' => {
'command-line' => 'drive_add auto "file=/dev/zvol/rpool/data/vm-20000-disk-1,if=none,id=drive-nvme1,format=raw,cache=none,aio=native,detect-zeroes=on"'
},
'execute' => 'human-monitor-command'
};
and I get:
"Duplicate ID 'drive-nvme1' for drive"
although it does not show up in query-block or query-pci anymore after
the first detach.
Is this a bug or am I missing something? Please advise.
Best regards,
Oguz
