similar to: QEMU guest-agent safety in hostile VM?

Where can I find the full list of libvirt supported qemu-ga commands? The docs [0] imply virDomainQemuAgentCommand bypasses libvirt and is not recommended. I am looking to pass suspend/resume events from the host to the guest and then have the guest act on this internally. Your help is appreciated. [0] https://wiki.libvirt.org/page/Qemu_guest_agent

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

Hello I have the following problem : group the lines of a dataframe when no information change (Matricule, Nom, Sexe, DateNaissance, Contrat, Pays) and when the value of Debut of lines i = value Fin of lines i-1 I can obtain it with a do loop. Is it possible to avoid the loop ? The dataframe initial is df1 dput(df1) structure(list(Matricule = c(1L, 1L, 1L, 6L, 6L, 6L, 6L, 6L, 6L, 8L, 8L, 8L,

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. 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''ve a problem with this : [code] def fir_tahiti @notams=Array.new Notam.find_all_notams().each do |notam| @notams.push(notam) if (to_secs(notam.debut)<Time.now.to_i and to_secs(notam.fin)>Time.now.to_i) end end def to_secs(str = nil) Time.gm(2000+str[0..1].to_i, str[2..3].to_i, str[4..5].to_i, str[6..7].to_i, str[8..9].to_i).to_i if str end [/code] It tells

I've a problem with my X100P card. I'm setting up a VoIP to PSTN gateway,with oh323. This works, but when I call an PSTN phone number, some digits are duplicated, so I'm unable to call the right person. Not very clear ? I'll try to do better (sorry, I'm french...) example : I use ohphone (with quicknet hardware), I call asterisk (*192*168*1*204#), asterisk answers, I choose

Hi, I recently won the Railsday contest and the response has been overwhelming.

I'm trying to put together a poster using the LaTeX a0poster package and including some things from pstricks to get gradient shading, etc. The problem is that the default environments used by Sweave don't work where I need them. A simple code chunk like <<eval=FALSE>>= x <- 1 @ buried in a minipage within a psshadowbox gives the error Runaway argument? > x <- 1

Has anyone found a softphone that supports pulling it's configuration from a central server via TFTP/FTP/HTTP, much like hard desk phones use? I'm looking for something for a call center that I can provision from a central location by generating config files. If the phone has "soft keys" (yes, I know they're all soft - but you know what I mean; programmable buttons whose

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

Consider this topology domain1-server1 domain2-server2 | | laptop - domain1-server1 ---- domain2-server1 Laptop has two ssh identities, domain1 and domain2. I don't wish to store identity locally in any of the servers. As far as I understand, there isn't any way to limit ssh-agent to allow only signing

Hello, I have a question about how R can run automatically. Here is the story: A file called "data.csv" will be generated every couple of minutes in a folder (overwrite itself). What I want R to do is: 1) scan the folder to find the file. 2) if the file is a newly generated file, process the file 3) output some file identifier on the screen, such as the time when the file was

Hello, I encountered errors when building rpm on fedora33: Versions: libvirt: v6.9.0-rc2 gcc-10.2.1-5.fc33.x86_64 meson-0.55.3-1.fc33.noarch ninja-build-1.10.1-2.fc33.x86_64 binutils-2.35-11.fc33.x86_64 Steps: 1.
