Title:
qemu-img V1.0 hangs on creating Image (0.15.1 runs)
Status in QEMU:
New
Bug description:
Hi,
i try the following command:
/usr/bin/qemu-img create -f qcow2 test.img 10G
if i run it on V0.15.1 it works, on V1.0 it hangs. Starting qemu-kvm
hangs too, i think it's the same Bug.
Strace on the hanging qemu-img ends on:
select(5, [4], [], NULL, NULL) = 1 (in [4])
read(4, "\0", 16) = 1
close(3) = 0
open("test.img", O_RDONLY|O_NONBLOCK) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=131072, ...}) = 0
close(3) = 0
open("test.img", O_RDONLY|O_NONBLOCK) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=131072, ...}) = 0
close(3) = 0
stat("test.img", {st_mode=S_IFREG|0644, st_size=131072, ...}) = 0
open("test.img", O_RDWR|O_CLOEXEC) = 3
lseek(3, 0, SEEK_END) = 131072
next line in the strace on working qemu-img V0.15.1 is:
pread(3,
"QFI\373\0\0\0\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\20\0\0\0\0\0\0\0\0"..., 512, 0)
= 512
...
The only linking difference i see is the libgthread on the new version
V1.0. I am using glib V2.26.
Can someone help ?
best regards,
Michael
