[PATCH] conf: snapshot/checkpoint: Rewrite 'AlignDisk' logic to appease clang
by Peter Krempa 23 Aug '21

23 Aug '21

New clang has a false-positive about value of 'olddisks' being unused after being set. This is clearly wrong because we want to use 'g_autofree' to clear it later. While I'm against modifying good code for the sake of bad static analysis in this case it's not obvious that we depend on the lifetime of 'olddisks' being needed until the end of the function as we store pointers into it into the hash table and later copy them out. Rewrite the code by assigning to 'olddisks' earlier and then using 'olddisks' in the loop, so it's clear where the lifetime of the objects ends, and this should also silence the warning.

[libvirt][PATCH v6 0/6] Support query and use SGX
by Haibin Huang 23 Aug '21

23 Aug '21

This patch series provides support for enabling Intel's Software Guard Extensions (SGX) feature in guest VM. Giving the SGX support in QEMU is still pending for reviewing, this patch series is not submmited for code review, but only describe the SGX enabling solution design that contains changes to virConnectGetDomainCapabilities API response and domain definition. All comments/suggestions would be highly appreciated. Intel Software Guard Extensions (Intel® SGX) is a set of instructions that increases the security of application code and data, giving them more protection from disclosure or modification. Developers can partition sensitive information into enclaves, which are areas of execution in memory with more security protection. The typical flow looks below at very high level: 1. Calls virConnectGetDomainCapabilities API to domain capabilities that includes the following SGX information. <feature> ... <sgx supported='yes'> <epc_size unit=’KiB’>N</epc_size> </sgx> </feature> 2. User requests to start a guest calling virCreateXML() with SGX requirement. It should contain <devices> ... <memory model='sgx-epc'> <target> <size unit='KiB'>N</size> </target> </memory> ... </devices> Haibin Huang (3): Support to query SGX capability Add dommaincaps unit test add qemu capabilities version 5.2.0 Lin Yang (3): conf: Introduce SGX EPC element into device memory xml qemu: Add command-line to generate SGX EPC memory backend Add unit tests for guest VM

Questions about the ownership of /var/cache/libvirt/qemu
by Peng Liang 23 Aug '21

23 Aug '21

Hi all, When we change the user for QEMU process (change "user" and "group" in /etc/libvirt/qemu.conf) to a normal user, we found that libvirtd will also change the ownership of /var/cache/libvirt/qemu but will keep the ownership of /var/cache/libvirt/qemu/capabilities as root. Is it secure to put files/directories owned by root in a directory owned by a normal user? Could the normal user replace the root's file with a new one? Does it need to set sticky bit on /var/cache/libvirt/qemu or keep the ownership of /var/cache/libvirt/qemu as root?
