-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, maybe this is an old fart, but I cant get it to work. I am running libvirt on a laptop, where a dnsmasq is already running to delegate dns info for my local (not-public) network. My resolv.conf (on the host) lists the system-dnsmasq as first server. I had to set the listen-adress for the system-dnsmasq to 127.0.0.1 and set

I've been struggling for several days, trying to get native exceptions to work in my code. I managed to boil down the IR to the simplest possible example that I can think of. If anyone on this list can tell me what changes I need to make to the following code to get it to work (i.e. return 0 instead of a bus error), it would make my life immensely better. ; ModuleID =

Hi Talin, You're not using the llvm intrinsics for exception handling, so your code won't work. Using _Unwind_RaiseException should be OK, but your main function must at least use llvm.eh.exception, llvm.eh.selector.i32/64 and probably __cxa_begin_catch and __cxa_end_catch.

Hi all, What options exists under CentOS hosts to work with isolated networks?. For example, on BSD systems it is really trivial. In FreeBSD you can use setfib tools and on OpenBSD it is possible to use rdomain options. In 30 secs it is possible to work with isolated networks and assign process, ip address and routes (hidden from the main route table and ip addresses), etc. But I can't

Greetings, I've setup an vm with openwrt in it, defined a isolated lan between the vm and the host and booted the vm up. I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest. I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see: dagg@NCC-5001D ~ $ dhcpcd vnet0 DUID

Hello, I already wrote regarding that, but maybe it sounded too complex. I will write it a bit softer now. The replication through dsnyc works perfectly with one exception. I am having an issue with the replication of the subscriptions file on shared folder. We have a public mailbox defined: namespace public-test { location = maildir:/opt/mail/_public/test prefix = public/test/

Okay. Thanks. Do we have any facility APIs to set the DHCP Options via XML ? Default gateway ? Dns-server ? domain-name ?

.... I am getting a bit tired of those pesky DNSmasq entries in my syslog file, they fill it up about weekly, wash other stuff out of view on a tail. Is there any way to suppress them. or else increase their lease time so that they happen less frequently ? Having a finite lease time for a VM seems nonsensical, it can't go anywhere or disconnect (obviously) .... I tried restarting DNSmasq,

I have created a routed virtual network. From within the routed net, DNS requests to the dnsmasq interface virbr2 work fine. On the libvirt host, DNS requests to the dnsmasq interface virbr2 work fine. I would like to allow external hosts, on the same network as the libvirt host, to query the dnsmasq interface. However external DNS queries to the virbr2 interface time out. The iptables firewall

Hi all, I went through the docs but could not find a way to pass the -h OR --no-hosts option to dnsmasq via libvirt xml Is there a way to do this via xml ? please can someone help. Thanks

Hi, I have the following configuration in the xml of the guest. But if I set a static ip on the guest, then the guest can not access the outside network. I don't find an example on how to set a static IP address for the guest. Could anybody know how to modify the following xml code to do so? Thanks. 41 <interface type='network'> 42 <mac

Hello All- I've looked in several places and haven't found an answer to this question: is it possible to have libvirt add custom rules to iptables for virtual network interfaces? I took a look at the "Firewall and Network Filtering in Libvirt" page and it seems overly complicated for what I want to do. Given an interface virbr2 and its network 192.168.4.0/24, libvirt installs
