我有一个使用 qemu-img 创建的 VHD 磁盘，使用 qemu-img，我看到的大小为
vmdkDisk="xxxxxxx-disk1.vmdk"
vhdDisk="xxxxxxx-disk1.vhd"
qemu-img convert -f vmdk -O qcow2 $vmdkDisk image.qcow2
# -- resize raw image
qemu-img resize -f raw image.qcow2 8g
# -- convert raw disk to VHD
qemu-img convert -f raw -o subformat=fixed,force_size -O vpc image.qcow2 $vhdDisk
qemu-img info -f vpc --output json xxxxxxx-disk1.vhd
{
"virtual-size": 8589934592,
"filename": "xxxxxxx-disk1.vhd",
"format": "vpc",
"actual-size": 5870948352,
"dirty-flag": false
}
所以我知道以 MB 为单位的虚拟大小是 8589934592/1024/1024=8192MB
但是，当我尝试将 VHD 上传到 azure 存储容器时，出现以下错误
az storage blob upload-batch --account-name yyyy \
--account-key 0000000== \
--destination vhd --source . --type page

如果我试了167816/512= 327.765625，那么确实不是整数
但是，这里的 blob 大小是如何计算的？
谢谢！
az storage blob upload-batch --account-name yyyy \
--account-key 0000000== \
--destination vhd --source . --type page \
--pattern *.vhd
我放弃添加文件模式过滤器和azcli将nohup日志与vhd一起上传，导致错误。
