Hi Han, The slirp-helper is a helper program provided in libslirp rust bindings. It seems that you need to build it yourself ATM. git clone https://gitlab.freedesktop.org/slirp/libslirp-rs.git > cd libslirp-rs > cargo build --bin slirp-helper --features=all > Han Han <hhan@redhat.com> 於 2019年11月7日 週四 下午2:01寫道： > For the libvirt 5.8 release, I find that there is a new comment

Hi, I am using python apis. I can't seem to find equivalent python function for virDomainGetGuestInfo() https://libvirt.org/html/libvirt-libvirt-domain.html#virDomainGetGuestInfo I have qemu-guest-agent running on the guest, and want to extract os information.

There's a heap overflow in qemu SLIRP which affects libguestfs, potentially allowing a malicious filesystem to take control of the confining qemu process and from there attack the host. It will affect libguestfs specifically when these two conditions are both met: - You're using the ‘direct’ backend. - Networking is enabled. The direct backend is the default upstream, but not in

Hi! If i want to use bridged network or openvswitch, does guestfwd only works with slirp network? Or how it work in case of using bridge/openvswitch? <devices> <channel type='unix'> <source mode='bind' path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> </devices>

Let's actually compile and test the patch this time, rather than trusting the RHEL 7.6 patch to apply directly to head ... Rich.

qemu in SLIRP mode offers DHCP services to the appliance. We don't use them, but use a fixed IP address intead. This changes the appliance to get its IP address using DHCP. Note: This is only used when the network is enabled. dhclient is somewhat slower, but the penalty (a few seconds) is only paid for network users. We could consider using the faster systemd dhcp client instead. ---

Possibly for post 1.40. Rich.

Hello everybody, I am wondering if libvirt community implement features specefic to only one supported hypervisor? I am trying to set the host name and DNS from within the libvirt xml file in user mode network option (SLiRP). Right now I am using the <qemu:commandline>. My concern is if I want to use Xen or other hypervisors, how I should do the same. To be honest, I have not used any

Hi: I noticed a bug in the realloc error checking code in the QEMU backend for RealTek8139. However, what''s worse is that there is no cap on the total size of the transmit buffer at all. So a guest can keep extending it until memory runs out. CP_TX_BUFFER_SIZE is already 64K. So it seems to me that we don''t need the while loop to extend the buffer at all since no transmitted

Dear all: I am trying to migrate a WinXP HVM (64M memory) from a machine (sender) to another machine (receiver) through AoE disk, however, there are some errors when do the following command: (My xen version is xen-4.0.1-rc5.hg, kernel 2.6.31.13, xen xen-4.0.1-rc6-pre, Both sender and receiver are the same xen version) xm migrate --live domain_id receiver_ip
