Hi all, Recently, I did some convergence tests of VM lifecycles and storage anomalies. Here is a question about the qemu core. The VM configure disk of IP SAN storage device.
Call traceļ¼ #0 0x00007fbe9151877b in raise () from /usr/lib64/libc.so.6 #1 0x00007fbe91519aa1 in abort () from /usr/lib64/libc.so.6 #2 0x00007fbe9151103a in ??

() Backtrace stopped: Cannot access memory at address 0x7fbdf1e00000 The scsi cmd requested in the core is inqury, the cmd is to call " handle_aiocb_ioctl(void *opaque) ". When the network is abnormal, the senses may not be obtained. This will cause " r->io_header.sb_len_wr " is 0, qemu core occurs. We can fix this bug by deleting " assert(in_len > 0); ". Any better suggestion? Thanks
