Hi, I tried to run domsuspend command on my PowerPC board but failed. # virsh dompmsuspend sdk --target mem error: Domain sdk could not be suspended error: argument unsupported: QEMU guest agent is not configured It seemed that support suspend-to-mem only from capabilities. # virsh capabilities <capabilities> <host>

Hi, I was going through the maillist[0] and found virDomainQemuAgentCommand() support function added to python module. I also checked the API documentation and didn't able to find any pointer for this particular function. Is API documentation[1] not updated with these function details yet or I am looking to a wrong place? Another question is I am using libvirt-1.0.5.5-1.fc19.x86_64 and

Hello, I need to communicate with windows 10 guest from cent os host. Following this docs - https://access.redhat.com/solutions/732773, https://wiki.libvirt.org/page/Qemu_guest_agent I add new device in my Win10 guest <channel type='unix'> <target type='virtio' name='org.qemu.guest_agent.0'/> </channel> and install gemu-ga x64 from this iso -

Hello. I'm a distro maintainer and was wondering about the efficacy of entropy daemons like haveged and jitterentropyd in qemu-kvm. One of the authors of haveged [0] pointed out if the hardware cycles counter is emulated and deterministic, and thus predictible. He therefore does not recommend using HAVEGE on those systems. Is this the case with KVM's counters? PS. I will be setting VM CPU

Hi I'm a privacy distro maintainer investigating the implications of the newly published nethammer attack [0] on KVM guests particularly the virtio-net drivers. The summary of the paper is that rowhammer can be remotely triggered by feeding susceptible* network driver crafted traffic. This attack can do all kinds of nasty things such as modifying SSL certs on the victim system. * Susceptible

Hi fellow libvirt users, I'd like to ask, whether somebody possibly dealt with similar problem we're hitting.. Some of libvirt VM operations (ie fs freeze) are prone to hang for long time, in case the guest agent is in some bad state.. My question is, if it's possible to set some timeout for such operations, or we have to deal with it ie with separate thread and some timers? we're

Hi, I'm trying to find out how to enable fstrim support for libvirt/qemu guests. Specifically I'm trying to enable this on a CentOS 7 host (qemu 1.5). I searched the web but only found very vague information and no clear documentation on the requirements or how to modify the guest xml to enable discard/fstrim support. Can someone point me in the right direction? Regards, Dennis

Hello. I'm interested in running guests as read-only to turn them into a sort of virtualized "live=cd". The goal is to leave no forensic evidence on the host disk or virtual one which would lead to traces on the host still- similar to how TAILS works but with the added convenince and flexibility of running in a VM. If I set the qcow image to read-only as per the manual, will any

Hi. I am very interested in the security properties a totally open TPM can give our users? - its use as a universal smartcard to protect all types of keys. When adding the virtual 1.2 or 2.0 TPM I get the vague error below. OS is Debian stable with standard packages. Error starting domain: Unable to find 'swtpm' binary in $PATH: No such file or directory Traceback (most recent call

Hi, I'm trying to get some basic data from running guests on a libvirt HV but one thing I'm missing is the name of the network interfaces of the guests. I can get the MAC address from the XML but there seems to be no function to actually get the name of the interface. The only function that comes close is this one:

if I understand correctly then I shouldn't have installed libvirt-daemon on the guests VMs? On Tue, May 12, 2020 at 2:34 PM Daniel P.
