From 5904676d2f018139afc1119017b9d60a3959cea2 Mon Sep 17 00:00:00 2001 From: Praveen K Paladugu Date: Fri, 11 Oct 2024 13:13:11 -0500 Subject: [PATCH] ch: explicitly set INFILESIZE to 0 While sending API requests that don't need any body, explicitly set CURLOPT_INFILESIZE to 0. Without this option, curl sends a chunked request with `Expect: 100-continue` header. The client, in this case curl, expects a response from the server, ch in this case, to respond within a timeout period. If guest definition has a PCI passthrough device configuration, cloud-hypervisor process cannot respond within above mentioned timeout. Even if cloud-hypervisor responds after the timeout, curl cannot read the response. Because of this, virsh request to create a guest, hangs. This only happens while using "mshv" hypervisor. By setting CURLOPT_INFILESIZE to O, curl drops the Expect header and sychronously waits for server to respond.
